PEEFACS, 


MUCH  perplexity  and  difficulty  has  been  felt  by  suiYeyors 
in  the  use  of  the  Magnetic  Compass,  in  consequence  of  it? 
variations  from  the  true  meridian,  at  various  localities  or 
stations,  and  also  its  almost  constant  diurnal  changes  as  well 

/  o 

as  aberrations,  caused  by  local  attraction.  A  more  perfect 
guide  for  the  surveyor  than  the  Magnetic  Needle  was,  there- 
fore, very  desirable.  The  long  continued  efforts  made  by 
the  author  to  accomplish  this  object,  resulted  in  the  inven- 
tion of  the  Solar  or  Astronomical  Compass.  A  model  of 
this  instrument  was  made  in  the  year  1835,  by  the  inven- 
tor, in  order  to  test  its^riftcijjGe,  and  in  the  latter  part  of 
the  same  year,  the  first  Solar  Compass  was  made,  under  his 
direction  and  supervision,  by  William  J.  Young,  of  Phila- 
delphia, Pa.  The  instrument  was  then  submitted  to  a  com- 
mittee of  the  Franklin  Institute,  of  the  State  of  Pennsyl- 
vania, who  after  a  full  examination  of  its  principles  and 
merits,  awarded  the  inventor  a  premium  of  twenty  dollars 
and  a  "Scott's  Legacy"  medal.  The  Solar  Compass  as  then 
made,  like  mcst  newly  invented  instruments,  was  soon  found 
susceptible  of  improvement  and  of  greater  usefulness  than 
at  first  anticipated.  Accordingly  the  inventor  made  se- 
veral alterations  and  improvements  suggested  by  experience, 
and  in  December,  1840,  again  submitted  the  instrument,  as 
improved,  to  a  committee  of  the  same  Institute,  who  re- 
ported a  decided  improvement,  in  point  of  accuracy,  and 
the  simplicity  of  its  adjustments  and  use.  The  inventoi 


IV  PREFACE 

has  since  continued  to  improve  tins  instrument  as  more  ex- 
perience in  the  use  of  it  seemed  to  suggest.  And  in  1851 
exhibited  it,  as  improved,  at  the  World's  Fair,  in  the  city 
of  London,  where  a  premium  medal  was  awarded  the  ex- 
hibitor by  the  jurors  on  Astronomical  Instruments. 

Since  its  invention  in  1835,  and  during  its  progressive 
improvements,  the  inventor  has  been  called  upon,  personallj 
or  by  letter,  from  a  large  portion  of  the  surveyors  of  the 
public  lands,  for  information  how  to  adjust  and  use  it.  Such 
inquiries  could  be  but  imperfectly  answered  by  letter,  or  a 
few  hours'  conversation,  and  the  author  could  not,  without 
being  discourteous,  avoid  replying  in  some  manner  to  such 
necessary  inquiries,  though  a  serious  tax  sometimes  on  his 
business.  To  prevent  this  the  inventor  published  a  few 
pages  of  instructions,  showing  how  to  adjust  and  use  this 
instrument,  and  distributed  them  among  the  surveyors;  but 
soon  after  this,  new  discoveries  were  made  in  the  construc- 
tion and  adjustments  of  the  Solar  Compass,  consequently 
what  had  been  done  only  supplied  their  wants  in  part,  and 
the  inventor  was  solicited  by  many  of  the  surveyors  of  the 
public  lands  for  full  instructions  on  this  subject,  and  a  trea- 
tise on  surveying  adapted  to  their  wants  in  the  field  of  sur- 
vey. The  foregoing  remarks  constitute  the  apology  of  the 
author  for  assuming  a  task  so  foreign  to  his  habits  of  lifs, 
and  to  which  duty  seemed  to  impel  him  in  the  absence  of 
any  prospects  of  this  much  needed  work  being  soon  accom- 
plished by  any  other  person.  This  treatise  contains  much 
original  matter,  mostly  derived  from  experience  in  practical 
surveying.  The  elements  of  surveying  as  published  and 
taught  in  the  schools,  are  purposely  omitted  to  lessen  the 
size  of  this  work,  the  object  of  which  is  to  furnish  the 
practical  surveyor  with  a  convenient  pocket  companion  suited 
to  his  business  while  engaged  in  his  field  work.  The  inex- 
perienced surveyor  in  this  branch  of  the  public  service  has 


PREFACE.  t 

need  of  all  necessary  information  to  enable  him  to  accom- 
plish his  arduous  duties  in  a  proper  manner.  The  frequent 
failures  in  part,  or  in  whole,  by  many  Deputy  Surveyors,  have 
done  much  injury  to  the  public  surveys,  and  ruined  their 
hopes  and  reputation. 

This  is  a  sufficient  reason  for  introducing  into  this  work 
the  necessary  outfit  and  preparations  for  a  large  survey  in 
the  wilderness,  the  want  of  which  has  been  one  of  the  prin- 
cipal causes  of  these  failures. 

The  author  does  not  presume  that  this  treatise  is  without 
defects-;  he  indulges  the  hope,  however,  that  it  will  answer 
the  purpose  for  which  it  is  designed,  until  further  experience 
shall  furnish  a  better.  The  author  has  availed  himself  of 
the  experience  of  several  practical  surveyors,  in  preparing 
this  work,  and  has  also  consulted  the  best  authorities  that 
appeared  to  throw  light  upon  the  subjects  treated  of. 

The  tables  of  Natural  Sines  and  Tangents,  at  the  end  of 
the  work,  have  been  carefully  compared  with  different  standard 
works,  and  are  offered  to  the  surveyor  with  a  confidence  that 
he  will  find  them  accurate.  The  table  of  chords  has  been 
added  to  supply  a  want,  frequently  experienced,  in  draught- 
ing, where  a  reliable  protractor  is  not  at  hand.  The  majority 
of  protractors  accompanying  draughting  instruments  are 
either  so  small  or  so  inaccurate  as  to  be  productive  of  sensi- 
ble errors  in  large  draughts.

THE  SOLAE  COMPASS  DESCRIBED. 

SEE  PLATE  I. 

The  Solar  Compass  works  astronomically  in  determining  latitude, 
and  in  measuring  horizontal  angles  from  the  true  meridian,  and  in 
determining  the  declination,  and  hour  arcs,  of  celestial  objects  within 
the  Zodiac;  and  is  further  used  as  a  magnetic  compass.  This  in- 
strument is  used  on  a  tripod,  with  a  ball  and  socket,  in  order  tc 
adjust  it  readily  to  an  approximate  level  by  the  hand,  after  which  it 
is  adjusted  to  a  true  level  by  means  of  four  thumb-screws  at  the 
lower  end  of  the  socket,  by  which  it  is  attached  to  the  tripod.  No 
part  of  these  are  seen  in  the  plate,  except  the  ball,  clamp  and  screw, 
at  u.  This  clamp  fastens  the  instrument  on  the  tripod  in  any  re- 
quired position.  The  Solar  Compass  has  two  main  plates,  seen  at 
a.  and  b.—a.  is  the  upper  and  b.  the  under  plate,  the  latter  is  that  on 
which  the  compass  sights  cc.  are  attached  by  screws  and  steady 
pins.  This  plate  revolves  underneath  the  upper  plate  on  a  conical 
centre  piece,  and  may  be  clamped  to  it  at  any  required  angle  by 
two  clamps,  one  of  which  is  seen  at  p.  There  is,  also,  an  inlaid  sil- 
ver ring  on  the  under  plate,  divided  into  half  degrees,  which  is  co- 
vered by  the  upper  plate,  except  at  two  openings  at  opposite  points, 
with  a  vernier  attached  to  each,  d.  d.  Upon  the  upper  plate  is  at- 
tached a  needle-box,  e,  by  a  conical  centre  piece  below  the  cap  of 
the  needle  q.  This  needle  has  an  arc  of  about  36°,  divided  into 
halves,  for  its  north  end  only.  A  lever,  r,  is  to  raise  the  needle  from 
its  pivot  when  not  in  use. 


10  THE   SOLAR   COMPASS. 

The  needle-box  has  a  limb  extending  at  right  angles  from  its 
centre,  which  is  not  seen  in  the  plate.  At  the  end  of  this  limb  is  a 
vernier  and  arc  to  set  off  the  needle's  variation ;  the  tangent  screw 
to  this  limb  and  vernier  is  seen  between  k  and  d.  In  consequence 
of  the  imperfection  of  magnetic  needles,  the  arc  is  attached  to  the 
upper  plate  by  two  screws,  and  made  adjustable,  so  that  all  instru- 
ments of  this  kind  can  be  made  to  read  the  same  magnetic  variation. 
On  the  upper  plate  two  adjustable  spirit  levels  are  placed  at  right 
angles  to  each  other,  for  the  purpose  of  adjusting  the  instrument  to 
a  true  level,  when  an  observation  is  made  on  any  celestial  object. 
The  edge  of  the  upper  plate  is  divided  to  every  five  degrees  of  a 
circle;  and  in  its  centre  is  placed  a  brass  pin,  rising  a  little  above 
the  needle-box;  by  this  arrangement,  the  surveyor  can  readily  see 
the  approximate  course  of  any  object  in  view,  without  turning  the 
sights  in  its  direction. 

Together  with  the  foregoing  described  parts,  on  the  upper  plate 
is  placed  the  solar  apparatus,  which  is  attached  to  it  by  two  small 
blocks,  fastened  by  screws  and  steady  pins,  one  of  which  is  seen  at  y. 
Into  each  of  these  blocks  one  axis  of  the  latitude  arc  g  enters 
These  axes  are  connected  by  the  hour  arc  i  and  two  radial  arms  z  z 
from  its  centre  at  s.  From  this  centre  of  the  hour  arc,  a  curvili- 
near arm  extends  to  the  latitude  arc  g.  The  latitude  arc  moves  in  a 
grooved  arc  to  which  its  vernier  t  is  attached.  The  grooved  arc  is 
fastened  to  the  compass  plate  by  a  flange  at  its  base,  and  two  screws. 
The  latitude  arc  g  has  a  radius  of  about  five  inches,  and  is  divided 
into  quarter  degrees,  and  its  vernier  t  reads  these  divisions  to  mi- 
nutes. The  latitude  arc  is  clamped  at  any  required  latitude,  by  a 
clamp  screw  on  the  back  side,  not  seen  on  the  plate.  The  hour  arc 
i,  as  above  stated,  lies  between,  and  connects  the  axes  of  the  latitude 
arc:  it  is  only  a  portion  of  the  hour  circle,  and  is  divided  to  half  de- 
grees. This  arc  gives  the  hour  angle  of  celestial  objects  within  the 
Zodiac  of  about  55°  or  60°  east  and  west  of  the  meridian. 

The  revolving  limb  v,  with  its  declination  arc  A,  is  mounted  on 
the  centre  of  the  hour  arc,  and  has  a  free  motion  on  its  conical 
Bpindle  or  axis,  within  the  conical  socket  s,  at  the  lower  end  of  which 
is  a.  collar  and  screw,  for  the  purpose  of  giving  a  suitable  tenseness 
to  its  movement.  This  is  called  the  polar  axis. 

In  connexion  with  the  revolving  limb  is  another  moveable  limb  a% 
attached  to  it  by  a  short  conical  centre  at  Z;  the  other  end  with  its 
vernier  m,  moves  over  the  declination  arc  h,  and  is  clamped  to  it  at 


SOLAR    COMPASS    BRIEFLY    EXPLAINED.        11 

any  required  declination,  by  a  clamp  screw  on  the  back  side  of  the 
arc.  This  arc  has  about  the  same  radius,  and  the  same  divisions 
and  vernier  as  the  latitude  arc. 

A  small  brass  plate  is  attached  by  screws  to  each  end  of  the  liml 
x,  standing  out  at  right  angles  from  the  limb ;  and  into  the  upper 
half  of  one  plate,  and  the  lower  half  of  the  other,  is  set  a  small  con- 
vex lens,  as  seen  at  o  o,  called  the  solar  lenses;  and  on  the  opposite 
brass  plate  to  each  lens,  is  attached  a  small  adjustable  silver  plate 
by  means  of  three  screws.  On  each  of  these  silver  plates  two  sets 
of  parallel  lines  are  drawn,  crossing  each  other  at  right  angles,  at  a 
suitable  distance  apart  to  embrace  the  sun's  image,  which  falls  be- 
tween them  from  the  lens. 

The  set  of  lines  which  are  parallel  to  the  hour  arc  are  called  the 
equatorial  lines,  and  the  set  which  are  vertical  to  the  hour  arc  are 
called  the  hour  lines.  On  the  upper  edge  of  each  brass  plate  above 
named,  is  placed  an  equatorial  sight  w  w,  which  can  be  attached  or 
detached  at  pleasure,  by  means  of  small  thumb  screws. 

There  is  also  another  limb  (not  seen  in  the  plate)  called  an  ad- 
juster, which  can  be  substituted  in  the  place  occupied  by  the  limb  x,  - 
for  the  purpose  of  adjusting  to  a  parallelism  with  the  lenses,  the 
equatorial  lines  on  the  silver  plates.  It  is  a  brass  bar  about  six 
inches  long,  and  one-fourth  of  an  inch  thick,  with  a  plane  surface, 
and  three  small  pins  at  each  end.  The  pins  are  for  the  purpose  of 
keeping  the  limb  x,  when  on  the  adjuster,  in  its  place. 

The  adjuster  when  used  must  be  attached  to  the  same  place  occu- 
pied by  the  limb  £,  with  the  same  centre  and  screws  that  held  the 
latter.  (See  second  adjustment.) 


PRINCIPLES  OF  THE  SOLAR  COMPASS  BRIEFLY 
EXPLAINED 

Where  a  solar  compass  is  correctly  adjusted  in  all  its  parts,  and 
also  to  the  latitude  and  meridian  of  the  place  of  observation,  wita 
its  vernier  m,  of  the  declination  arc  clamped  at  0,  or  zero,  then  the 
polar  axis  s,  of  the  instrument,  will  be  parallel  to  the  axis  of  the 
earth,  and  the  moveable  limb  x,  with  its  lenses  and  equatorial  sights, 
will  consequently  be  at  right  angles  to  the  polar  axis,  and  will  re- 
rohe  on  this  axis  parallel  to  the  plane  of  the  equator ;  therefore,  it 


12  THE    SOLAR    COMPASS. 

is  clear  that  this  motion  coincides  with  the  diurnal  motion  of  any 
heavenly  body  that  has  no  declination,  and  it  is  equally  clear,  that 
this  coincidence  holds  good  when  a  celestial  object  has  north  or 
south  declination,  if  its  decimation  be  set  off  on  the  declination  arc 
of  the  instrument;  vfor,  the  diurnal  motion  of  the  heavenly  object 
will  be  like  the  motion  of  the  moveablc  limb  x,  parallel  to  the  equa- 
tor and  equidistant  from  it.  Now  if  the  instrument  be  turned  hori- 
zontally out  of  the  meridian,  the  polar  axis  will  not  be  parallel  to 
the  axis  of  the  earth,  nor  will  the  moveable  limb  x  revolve  parallel 
to  the  equator;  consequently  it  will  not  follow  the  diurnal  motion  of 
any  heavenly  body ;  therefore,  if  the  sun's  declination  be  set  off  on 
the  declination  arc,  the  sun's  image  from  the  lens  will  not  fall  be- 
tween the  equatorial  lines  on  the  silver  plate,  but  will  fall  above  or 
below  them,  and  will  not  fall  between  them  until  the  compass  is 
turned  again  into  the  true  meridian. 

It  is  from  these  principles  cf  the  solar  compass  that  the  true  me 
ridian  is  obtained,  and  the  variation  of  the  needle  determined,  etc. 


ADJUSTMENTS  OF  THE  SOLAR  COMPASS. 

Before  using  the  solar  compass  it  must  be  correctly  adjusted. 
This  consists  in  bringing  its  different  parts  to  their  proper  place,  and 
in  determining  the  index  errors  of  the  instrument  in  its  graduated 
arcs,  which  is  chiefly  done  by  reversals  and  adjusting  screws. 

FIRST  ADJUSTMENT. 

To  adjust  the  two  spirit  levels  kk,  to  a  horizontal  movement  of  the  instru- 
ment on  its  lower  axis. 

Place  the  compass  on  the  tripod,  and  level  it,  or  nearly  so,  with 
the  hand,  then  by  means  of  the  levelling  screws  at  the  lower  end  of 
the  ball  and  socket,  bring  the  bubble  in  each  level  to  the  middle  of 
its  opening.  If  the  bubbles  do  not  move  while  the  compass  is  turned 
horizontally  around  on  its  lower  axis,  this  adjustment  is  right;  but 
if  they  move,  the  levels  must  be  adjusted  by  the  screws  at  the  end 
of  each  for  that  purpose,  until  the  bubbles  will  remain  stationary 
while  the  instrument  is  turned  horizontally  arsund. 


ADJUSTMENTS    OF    THE    SOLAR 

SECOND  ADJUSTMJ 

To  make  the  solar  lenses  and  the  equatorial  Iv 
parallel  to  each  other\\ 

Detach  the  limb  ar,  by  taking  out  its  fastening  screws,  and  attach 
the  adjuster  in  its  place,  with  the  same  screws  that  held  the  limb; 
then  clamp  it  at  the  moveable  end,  to  the  sun's  declination  as  near 
as  practicable.  Now  let  the  compass  be  placed  on  the  tripod  where 
the  sun  shines,  and  level  it,  with  the  sights  north  and  south,  or 
nearly  so ;  then  place  the  limb  x  on  the  adjuster,  between  the  pins, 
the  same  side  up  that  was  upon  the  compass,  and  then  bring  it  to 
bear  on  the  sun  as  in  other  observations,  and  turn  the  compass  hori- 
zontally, if  necessary  to  bring  the  sun's  image  precisely  between  the 
equatorial  lines  on  the  silver  plate ;  now,  without  moving  the  com- 
pass in  the  least  out  of  level,  or  otherwise,  take  the  limb  x  from 
the  adjuster  and  turn  the  upper  side  down,  without  changing  ends, 
and  place  it  on  the  adjuster  again;  then  see  if  the  sun's  image  falls 
between  the  equatorial  lines  as  before.  If  it  does,  this  plate  is  in 
adjustment;  but  if  it  does  not,  loosen- the  three  small  screws  which 
hold  the  silver  plate,  (having  oblong  holes  under  their  heads,)  and 
move  this  plate  one-half  of  the  observed  difference,  up  or  down  as 
the  case  requires,  and  lightly  tighten  the  screws  again.  Repeat 
these  observations  and  adjustments,  as  above  described,  until  the 
sun's  image  falls  precisely  between  the  equatorial  lines,  either  side 
up.  This  plate  then  will  be  in  correct  adjustment. 

Now  reverse  the  ends  of  the  limb  x,  and  adjust  the  other  silver 
plate  in  the  same  manner  as  the  first.  When  this  is  done,  the  paral- 
lelism of  the  lenses  and  equatorial  lines  are  as  perfect  as  reversals 
will  make  them,  and  the  equatorial  sights  are  also  parallel  to  these. 
The  adjuster  may  now  be  taken  off  and  the  limb  x  returned  to  its 
place.  It  will  not  be  necessary  to  repeat  this  adjustment  unless  the 
silver  plates  get  moved  by  accident  or  otherwise.  The  best  time  to 
make  these  adjustments,  is  between  the  hours  of  10  A.  M.  and  2  P.  M. 

In  making  this  adjustment  the  limb  x  should  fit  accurately  on  the 
adjuster,  and  the  brass  plates  in  which  the  lenses  are  set  must  be 
precisely  of  the  same  breadth;  if  they  are  not,  this  adjustment  can- 
not be  correctly  made.  Therefore,  these  plates  should  be  carefully 
tried  with  a  gauge,  and  any  difference  in  size  corrected.

14  THE   SOLAR   COMPASS. 

THIRD  ADJUSTMENT. 

To  find  the  index  error  of  the  declination  arc. 

FIRST   METHOD. 

Set  the  vernier  m  of  the  declination  arc  h  at  0,  or  zero,  place  the 
compass  on  the  tripod,  and  incline  it  north  or  south,  as  the  sun  may 
have  north  or  south  decimation,  until  the  sun's  image  falls  precisely 
between  the  equatorial  lines  on  the  silver  plate ;  then  reverse  the 
lenses  by  turning  the  revolving  limb  half  way  around,  and  see  if  the 
sun's  image  falls  precisely  between  the  equatorial  lines  on  the  other 
silver  plate;  if  it  does,  there  is  no  index  error  in  this  arc;  but  if  it 
does  not,  move  the  limb  x  up  or  down,  as  the  case  requires,  on  the 
declination  arc  one-half  of  the  observed  difference,  and  try  the  re- 
versals again,  and  so  repeat  them,  if  necessary,  until  the  sun's  image 
falls  precisely  between  the  equatorial  lines  on  both  silver  plates. 
The  amount  of  index  error  in  this  arc  can  now  be  read  by  its  vernier 
m.  If  the  index  error  is  below  the  graduated  zero  point  on  the  de- 
cimation arc,  its  amount  must  be  subtracted  from  the  declination  of 
the  celestial  object,  before  it  is  set  off  on  the  declination  arc;  but  if 
above,  it  must  be  added. 

SECOND  METHOD. 

Set  the  vernier  m  of  the  declination  arc  h  at  zero,  as  before,  and 
bring  the  equatorial  sights  to  bear  on  some  distant  object;  then, 
without  moving  the  compass  in  the  least,  reverse  the  revolving  limb 
v,  and  see  if  the  line  Of  sight  is  the  same  as  before ;  if  it  is,  there  is 
no  index  error;  but  if  not,  proceed  as  described,  by  reversals  on  the 
BUD,  until  the  equatorial  sights  will  bear  on  the  same  objects  when 
reversed. 

FOURTH  ADJUSTMENT. 

To  bring  the  polar  axis  to  a  right  angle  with  the  axis  of  the  latitude  arc. 
This  adjustment  generally  is,  and  always  should  be  made  by  the 
instrument  maker,  but  the  surveyor  should  test  his  instrument  in  all 
of  its  parts.  First  detach  the  solar  apparatus  from  the  upper  plate, 
by  taking  out  the  clamp  screw  of  the  latitude  arc,  and  the  screws 
that  fasten  its  axis  and  blocks  to  the  upper  plate;  then  take  a  piece 
of  board  about  four  inches  wide  and  a  foot  long,  with  smooth  edges, 
and  nail  one  edge  to  another  board  about  one  foot  square,  so  tha< 


ADJUSTMENTS    OF    THE    SOLAR    COMPASS.       II) 

it  will  be  at  right  angles  to  its  surface.  Place  this  on  a  stand  or 
table,  in  a  convenient  place  to  view  some  distant  object,  then  take 
the  blocks  that  hold  the  axes  of  the  latitude  arc,  and  place  them  on 
their  axes,  and  fasten  them  by  their  screws  to  the  upper  edge  of  the 
narrow  board ;  by  this  arrangement  the  polar  axis  s  can  be  brought 
to  a  perpendicular,  and  then  reversed,  by  giving  motion  to  the  aies 
of  the  latitude  arc  of  180°. 

The  nioveable  limb  x  must  now  be  clamped  to  its  true  zero  point, 
as  found  by  the  third  adjustment,  and  the  polar  axis  s  brought  to  a 
perpendicular ;  the  revolving  limb  v  must  now  be  turned  parallel  to 
the  axis  of  the  latitude  arc;  then  observe  some  distant  object  through 
the  equatorial  sights;  now  reverse  the  polar  axis  as  above  directed, 
and  see  if  the  equatorial  sights  bear  on  the  same  object  as  before 
reversing  the  polar  axis ;  if  they  do,  the  polar  axis  is  at  right  angles 
to  the  axis  of  the  latitude  arc;  but  if  not,  the  face  of  the  flange,  or 
the  seat  of  the  conical  socket  s,  must  be  ground  on  one  side  enough 
to  correct  this  error,  so  that  the  equatorial  sights  will  bear  on  the 
same  object  when  reversed  as  above  stated.  If  the  error  7oc  small, 
it  may  be  corrected  by  placing  a  thin  piece  of  tin  foil,  or  ?  jme  other 
firm  substance,  under  one  side  of  the  flange  of  the  conical  socket  s. 

FIFTH  ADJUSTMENT. 

To  make  the  compass  sights  coincide  with  the  true  meridian,  when  an  ob- 
servation is  made  with  the  solar  compass. 

Place  the  compass  on  the  tripod,  and  clamp  the  sights  to  an  east, 
west  course;  then  take  out  the  clamp  screw  to  the  latitude  arc,  and 
raise  this  arc  until  the  polar  axis  s  is  horizontal,  or  nearly  so,  and 
fasten  it  in  this  position,  which  can  be  easily  done  by  placing  a  small 
wedging  piece  of  wood  between  the  edge  of  the  hour  arc  and  the 
.  upper  plate  of  the  compass,  and  a  small  brace  of  wood  between  the 
brass'centre  pin  and  the  conical  centre  s  of  the  hour  arc.  Then 
clamp  the  vernier  m  of  the  declination  arc  at  its  true  zero  point,  as 
found  by  the  third  adjustment.  Now  bring  the  equatorial  sights  to 
bear  on  some  distant  object  in  or  near  the  horizon;  then  anclamp 
the  main  plates  a  and  b,  and  bring  the  compass  sights  to  bear  on 
the  same  distant  object;  (it  is  well  to  reverse  the  equatorial  sights 
and  make  the  same  observation  again;)  if  both  sights  still  coincide, 
read  at  the  verniers  d  d,  the  amount  of  the  index  error,  il  any.  be- 
tween these  plates. 


10  THE    SOLAR   COMPASS. 

This  adjustment  should  always  be  made  by  the  instrument  maker, 
and  cleared  of  index  error,  by  a  proper  adjustment  of  the  compass 
sights  on  the  lower  plate.  But  if  any  index  error  is  found  in  the 
instrument,  while  in  the  hands  of  the  surveyor,  it  should  be  allowed 
for  in  all  courses  run  by  him,  or  he  may  correct  it  by  removing  one 
of  the  compass  sights  the  required  amount  so  as  to  make  the  lino 
of  sight  to  coincide  with  the  meridian.  This  can  be  done  by  en- 
larging, with  a  small  round  file,  the  holes  on  one  side  of  the  steady 
pins  and  screw  that  hold  the  compass  sight  to  the  lower  plate, 
enough  to  correct  the  index  error.  The  vacancy  on  the  side  of  the 
steady  pins  may  be  filled  with  tin  foil,  or  some  other  substance  that 
is  not  magnetic. 

SIXTH  ADJUSTMENT. 
To  find  the  index  error  of  the  latitude  arc. 

This  is  most  correctly  done  by  determining  the  latitude  of  any 
station  by  north  and  south  stars,  or,  determine  the  latitude  by  the 
sun,  and  again  by  the  pole  star;  (see  article,  "  Latitude  by  the  Solar 
Compass;")  one-half  of  the  difference  of  latitude  thus  found,  if  any, 
is  the  index  error  of  this  arc.  If  the  latitude  determined  by  an 
observation  on  the  sun,  or  star  within  the  zodiac,  be  less  than  the 
latitude  by  the  north  star,  the  half  difference  must  be  added  to  the 
zodiacal  observation,  to  obtain  the  true  latitude  of  the  station;  but 
if  greater,  it  must  be  subtracted.  But  this  index  error  is  not  used 
for  any  other  purpose  than  to  find  the  true  latitude,  for  the  latitude 
given  by  an  observation  on  a  celestial  object  within  the  zodiac,  is 
the  latitude  to  be  used  for  all  other  purposes. 

SEVENTH  ADJUSTMENT. 

To  find  the  index  error  of  the  hour  arc. 

Adjust  and  clamp  the  compass  sights  to  the  true  meridian,  a§ 
directed  in  the  remarks  to  find  the  meridian,  variation  of  the  needle, 
&c. ;  also,  set  a  stake  in  the  meridian,  four  or  five  chains  south  of 
the  instrument,  and  keep  the  compass  sights  directed  to  it.  Then 
at  the  distance  of  ten  or  twelve  feet  south  of  the  instrument,  suspend 
a  plumb  line  from  the  top  of  a  suitably  inclined  pole  set  in  the  ground, 
find  firmly  supported  with  crotches,  and  of  a  sufficient  height  to  ob- 
serve, near  the  top  of  the  line,  the  meridian  passnge  of  the  sun. 
Then  with  the  aid  of  a  suitable  dark  glass,  observe  through  the 
Borth  sight  vane,  the  meridian  contact  of  the  sun's  west  limb  with 


ADJUSTMENTS    OF    THE    SOLAR    COMPASS.      17 

ihe  line,  while  an  assistant  has  kept  the  sun's  image  accurately  be- 
tween the  hour  lines  on  the  silver  plate.  At  this  point,  read  on  the 
graduated  side  of  the  declination  arc,  at  either  end  of  the  revolving 
limb,  its  distance  from  the  graduated  zero  point,  and  the  same  agahi 
with  the  last  contact  of  the  sun's  east  limb :  half  the  difference  on 
the  hour  arc,  between  these  two  observations,  will  be  its  true  zero 
point ;  from  which  read  the  index  error. 

It  should  be  remarked  here,  that  the  principles  of  the  solar  com 
pass  have  been  applied  in  various  ways  to  surveying  instruments, 
to  suit  the  views  of  mathematical  instrument  makers,  or  surveyors 
for  whom  they  were  made ;  but  the  solar  compass  described  in  the 
foregoing  pages,  and  for  which  the  adjustments  are  given,  has  been 
found,  after  much  experience  in  its  use,  to  be  the  best  adapted  to 
surveying  the  public  lands,  and  for  this  purpose  it  is  generally  used; 
for  the  reason  that  it  is  more  safely  and  conveniently  carried  and 
used  through  all  the  exposures  which  are  unavoidable  in  the  wilder- 
ness. Some  change,  however,  may  be  made  in  its  mechanical  con- 
structipn,  for  the  purpose  of  city  surveying,  and  for  running  the 
lines  and  curves  of  railroads,  etc.  But  in  whatever  form  they  may 
be  made,  it  is  important  to  a  good  solar  apparatus,  that  the  latitude 
and  declination  arcs  have  a  radius  not  less  than  five  inches,  so  that 
their  divisions  may  be  sufficiently  large  to  be  easily  read,  and  the 
arcs  readily  and  accurately  adjusted  for  use.  The  importance  of 
this  will  be  understood  by  considering  the  frequency  of  these  adjust- 
ments, and  the  circumstances  under  which  they  are  made  while 
running  lines  in  the  field.  So  far  as  known  to  the  author,  but  few 
surveyors  have  qualified  themselves  to  use  the  solar  compass  on  any 
other  celestial  object  than  the  sun;  and,  perhaps,  as  few  have  fully 
understood  its  principles  and  adjustments.  The  reason  of  this  is  found 
in  the  fact,  that  no  work  has  been  published  before  this,  sufficiently 
elucidating  its  principles,  adjustments  ard  use.  The  sun  is  the  prin- 
cipal celestial  object  used  in  surveying  lines  with  this  instrument, 
which  only  requires  a  knowledge  of  the  true  declination  of  the  sun 
for  each  hour  of  the  day,  in  the  longitude  where  the  survey  is  to  be 
made.  Therefore,  with  the  instructions  here  given,  no  accomplished 
surveyor  with  the  magnetic  compass,  need  hesitate  to  use  the  solar 
compass  on  the  sun;  and  he  will  soon  acquire  the  further  knowledge 
of  using  it  on  other  heavenly  bodies  at  night,  to  determine  the  va- 
liation  of  the  needle,  and  for  other  purposes  treated  of  in  this  work 
If  the  solar  compass  has  been  truly  adjusted  in  all  of  its  parts,  pr^.

THE    SOLAR   COMPASS. 


vious  to  its  being  used  in  the  field,  the  surveyor  may  feel  the  fullest 
confidence  in  the  true  course  of  his  lines  run  with  it. 


ASTRONOMY. 

Though  merely  a  knowledge  of  the  apparent  diurnal  motion  of 
the  sun  in  the  heavens,  will  serve  for  the  single  purpose  of  using 
the  solar  compass  on  that  luminary;  yet,  for  all  the  purposes  for 
which  this  instrument  can  be  employed  by  night  on  the  planets  and 
fixed  stars,  a  more  extended  knowledge  of  astronomy  is  required. 

Therefore,  the  following  brief  notice  of  astronomical  facts  and  phe- 
nomena is  deemed  necessary  to  be  understood  by  all  surveyors,  to 
enable  them  to  use  the  solar  compass  to  the  best  advantage. 

SOLAR  SYSTEM. 

The  sun  is  the  centre  of  the  solar  system,  around  which  all  the 
planets  revolve  in  elliptical  orbits,  from  west  to  east,*  with  dimi- 
nished velocities  as  their  distances  increase  from  the  sun :  the  planes 
of  their  orbits  are  nearly  coincident  with  the  plane  of  the  ecliptic  ; 
therefore,  their  greatest  declinations  will  be  sometimes  more  or 
less  than  the  sun's  greatest  declination,  by  the  amount  of  the  angle 
of  inclination  of  each  of  their  orbits  to  the  plane  of  the  ecliptic.

from  the  sun  moves  around  its  axis. 


ASTRONOMY. — EQUATOR.  19 

THE  EARTH. 

The  earth  is  an  oblate  spheroid,  whose  equatorial  diameter  ex- 
ceeds its  polar  diameter  about  26  miles ;  the  cause  of  this  difference 
is  supposed  to  be  the  centrifugal  force  of  the  earth's  rotary  motion 
around  its  axis. 

The  north  and  south  poles  of  the  earth  are  two  points  on  its  sur- 
face, opposite  to  each  other ;  and  a  straight  line  between  these  two 
points  is  called  the  axis  of  the  earth,  around  which  the  earth  re- 
volves, from  west  to  east,  once  in  a  sidereal  day. 

The  axis  of  the  earth  is  always  inclined  from  a  perpendicular  to 
the  plane  of  its  orbit;  in  other  words,  the  axis  of  the  earth  has  an 
angle  to  the  axis  of  the  ecliptic,  of  about  23°  28/.  Therefore,  the 
axis  of  the  earth  is  always  in  the  same  direction  in  regard  to  the 
heavens,  in  every  part  of  its  orbit. 

This  angle  of  inclination  causes  the  declination  of  the  sun  north 
and  south  of  the  celestial  equator,  during  each  revolution  of  tlio 
earth  around  the  sun.  It  is,  also,  the  principal  cause  of  the  decli- 
nations of  the  planets ;  the  different  seasons  of  the  year ;  and  the 
different  length  of  days  and  nights. 

EQUATOR. 

The  Equator  encircles  the  earth  at  right  angles  to  the  axis,  and 
is  equidistant,  or  90°  from  its  poles;  its  plane  divides  the  earth 
into  two  equal  parts,  called  northern  and  southern  hemispheres. 

The  plane  of  the  equator,  if  extended  to  the  heavens,  is  called  the 
celestial  equator,  which  has  an  angle  to  the  plane  of  the  ecliptic, 
(like  the  angle  between  their  axes)  of  about  23°  28'. 

The  motion  of  the  earth  around  its  axis  is  uniform ;  but  the  ve- 
locity of  the  earth  in  its  orbit  around  the  sun  is  unequal,  the  mean 
of  which  is  59X  8/x  each  day.  The  sun  will  therefore  return  to  any 
given  meridian  each  day  in  unequal  times ;  hence  the  difference  be- 
tween apparent  and  mean  time,  called  the  equation  of  time. 

A  tropical  year  is  365  d.,  5  h.,  48m.,  49  s.  A  sidereal  year,  rec- 
koned in  mean  solar  time,  is  365  d.,  6  h.,  9  m.,  9.  6s.,  and  reckoned 
in  sidereal  time,  is  366  d.,  6h.,  9m.,  9.  6s. 

The  reason  of  this  difference  is,  the  earth  has  moved  once  around 
the  sun  in  its  orfcit  the  same  way  the  equator  moves  around  its  own 
axis.  The  earth  must  therefore  complete  one  revolution  and  59' 
8/x  on  its  axis  each  day,  to  bring  the  sun  to  the  same  meridian 
This  is  called  solar  time. 


20  THE    SOLAR    COMPASS. 

The  earth  has  precisely  one  revolution  on  its  axis  from  the  transh 
of  a  fixed  star  to  the  next  transit  of  the  same  star,  which  is  a  bide- 
real  day  of  24  hours;  but,  if  reckoned  in  mean  solar  time,  it  is  23 h., 
56m.,  4s.,  9X//. 

An  astronomical  day  commences  at  noon,  and  is  reckoned  from 
one  to  24  hours  successively;  the  civil  day  commences  at  the  pre- 
ceding midnight,  and  is  reckoned  from  1  to  12  hours,  twice  in  a  civi 
day:  therefore  the  last  12  hours  of  the  civil  day  correspond  to  the 
first  12  hours  of  the  astronomical  day.  All  astronomical  calcula- 
tions are  computed  in  astronomical  time. 

LATITUDE. 

Latitude  on  the  earth  is  reckoned  north  and  south  of  the  equator 
in  degrees,  etc.,  of  the  meridian,  to  the  poles  (or  90°.)  Difference 
of  latitude  is  an  arc  of  the  meridian,  between  any  two  parallels  of 
latitude. 

LONGITUDE. 

Longitude  on  the  earth  is  reckoned  east  and  west  from  any  prime 
meridian,  in  arc  or  time  to  180°  or  12  hours.  Difference  of  lon- 
gitude is  the  difference  in  arc  or  time,  between  any  two  meridians, 
reckoned  on  any  parallel  of  latitude. 

ECLIPTIC. 

The  Ecliptic  is  a  great  circle  of  the  heavens,  and  its  plane  is  the 
extension  of  the  plane  of  the  earth's  orbit,  indefinitely,  into  space, 
or  the  starry  heavens. 

The  sun  is  always  in  the  ecliptic,  and  the  orbits  of  all  the  planet§ 
cut  or  intersect  the  ecliptic  at  opposite  points,  called  their  nodes,  in 
which  only  eclipses  occur. 

ZODIAC. 

The  Zodiac  is  an  imaginary  belt  or  circle  of  the  heavens,  and  oc- 
cupies a  space  of  8°  on  each  side  of  the  ecliptic ;  within  which  all 
the  planets  appear  to  perform  their  revolutions  around  the  sun. 

DECLINATION. 

Declination  of  a  heavenly  body  is  reckoned  north  and  south  of  the 
equatorial  plane.  The  complement  of  the  declination  of  a  celestial 
object  is  its  nearest  polar  distance. 


ASTRONOMY. — AZIMUTH.  21 

RIGHT  ASCENSION. 

The  right  ascension  of  heavenly  bodies  is  reckoned  in  time  from 
the  first  point  of  Aries,  or  the  vernal  equinox,  around  in  the  order 
of  the  signs,  on  the  equator,  to  the  same  point  again.  The  longitude 
of  heavenly  bodies  is  reckoned  from  the  same  point,  and  in  the  same 
order  on  the  ecliptic,  in  degrees,  etc.,  as  right  ascension  is  reckoned 
m  time  on  the  equator. 

ALTITUDE  AND  ZENITH  DISTANCE. 

The  altitude  of  a  celestial  object  is  the  angle  in  which  it  is  ob- 
served above  the  horizon.  The  zenith  distance  of  a  heavenly  body 
is  its  angular  distance  from  the  zenith,  or  point  directly  over  head 
of  the  observer. 

HORIZON. 

An  observer  has  two  horizons,  the  sensible  and  rational.  The 
sensible  horizon  is  a  circle  at  the  extent  of  view  in  all  directions,  on 
a  horizontal  plain,  or  on  the  ocean.  The  plane  of  the  rational  hori- 
zon divides  the  earth  into  two  equal  parts  through  its  centre,  paral- 
lel to  the  sensible  horizon ;  it  is,  therefore,  the  semi-diameter  of  the 
earth  below  the  sensible  horizon. 

REFRACTION  AND  PARALLAX. 

The  atmospheric  refraction  causes  a  heavenly  body  to  appear 
above  its  true  place  in  the  heavens,  except  it  be  in  the  zenith.  The 
parallax  of  a  celestial  object  is  the  difference  in  altitude  that  would 
appear  between  an  observation  made  from  any  point  on  the  earth's 
surface  and  from  its  centre.  Therefore,  parallax  causes  heavenly 
bodies  to  appear  below  their  true  place  in  the  heavens,  except  they 
are  in  the  zenith ;  hence  the  corrections  for  parallax  and  refraction 
of  instrumental  observations  on  celestial  objects. 

AZIMUTH. 

The  azimuth  of  a  heavenly  body  is  reckoned  on  the  horizon  of  the 
observer,  between  a  vertical  plane  of  the  meridian,  and  another  ver- 
tical plane  passing  through  the  centre  of  the  celestial  object,  to  the 
zenith  of  the  observer.  In  other  words,  it  is  the  true  bearing  of  a 
heavenly  body  referred  to  the  horizon  from  the  meridian. 


£2  THE   SOLAR   COMPASS. 

Azimuths  are  generally  reckoned  from  the  north  in  north  latitude, 
and  from  the  south  in  south  latitude. 

The  amplitude  of  a  heavenly  body  is  its  true  course  or  bearing  at 
rising  or  setting,  from  the  east  or  west  points  of  the  horizon. 

NAUTICAL  ALMANAC. 

Blunt's  Nautical  Almanac  and  Astronomical  Ephemeris,  (on  ac- 
count of  its  size)  is  the  most  convenient  that  has  yet  been  pub- 
lished for  the  surveyor  to  take  data  from,  for  the  use  of  the  solar 
compass.  The  heading  of  each  page  and  column  is  a  sufficient  ex- 
planation of  its  contents  and  use. 

This  almanac  is  adapted  to  mean  noon  at  Greenwich,  England, 
except  the  sun's  declination,  which  is  more  properly  given  for  ap- 
parent noon. 

It  will  be  seen  that  the  quantities  in  the  columns  are  continually 
varying  from  day  to  day;  therefore  some  reduction  is  necessary  to 
adapt  them  to  any  other  time  or  longitude,  than  that  for  which  they 
were  registered.  This  is  accomplished  by  applying  the  hourly  dif- 
ferences, where  they  are  given,  according  to  their  sign  or  precept ; 
and  where  the  hourly  diiferences  are  not  given,  take  the  required 
proportional  part  of  the  difference  between  the  preceding  and  suc- 
ceeding noon  at  Greenwich,  and  add  to  or  subtract  from  the  re- 
gistered quantities,  according  as  they  are  increasing  or  decreasing, 
as  the  case  requires. 

FIXED  STARS. 

The  following  table  of  the  mean  places  of  35  fixed  stars  has  been 
selected  from  the  Nautical  Almanac,  for  January  1st,  1854,  for  the 
purpose  of  night  observation  with  the  solar  compass.  The  sign  -f- 
prefixed  to  an  annual  variation  is  to  be  added  to,  and  the  sign  —  is 
to  be  subtracted  from  the  right  ascension:  also,  for  stars  having  north 
declination,  -|-  signifies  add,  and  —  subtract;  but  for  stars  of  south 
declination  -}-  denotes  that  the  variation  is  to  be  subtracted  from^  and 
—  that  it  is  to  be  added  to  the  declination.

LATITUDE  BY  THE  SOLAR  COMPASS. 

After  the  solar  compass  lias  been  correctly  adjusted  in  all  of  its 
parts,  ita  future  usefulness  depends  upon  finding  the  latitude  aa 
given  by  the  instrument,  at  the  place  where  it  is  used. 

That  it  may  not  be  repeated  again,  hereafter,  it  should  be  remarked, 
that  in  all  observations  with  the  solar  compass,  it  must  be  placed 
on  the  tripod,  and  accurately  levelled,  with  the  latitude  arc  turned 
toward  the  equator;  except,  that  when  making  an  observation  on 


24  THE    SOLAE   COMPASS. 

the  polo-star,  it  must  be  turned  in  that  direction.  This  can  be  done 
approximately  by  the  magnetic  needle. 

Thus  prepared,  set  off  the  sup's  decimation  for  noon  on  the  de- 
cimation arc,  allowing  for  its  index  error,  if  any,  and  the  sun's  me- 
ridional refraction,  also,  adjust  the  latitude  arc  approximately  to  the 
latitude  of  the  place,  and  the  revolving  limb  v.  at  its  true  zero  point 
on  the  hour  arc  i. :  in  other  words,  for  noon. 

Commence  the  observation  for  latitude  about  fifteen  minutes  be- 
fore the  sun  culminates,  by  turning  the  instrument  horizontally  on 
its  lower  axis,  so  that  the  sun's  image  will- fall  between  the  hour 
lines  on  the  silver  plate,  and  raise  or  lower  the  latitude  arc,  if  neces- 
sary, to  bring  the  sun's  image  between  the  equatorial  lines.  Then 
follow  the  motion  of  the  sun,  by  turning  the  compass  horizontally, 
at  short  intervals  of  time,  and  adjust  the  latitude  arc,  to  keep  the 
sun's  image  between  the  equatorial  lines,  until  he  culminates.  The 
latitude  of  the  station  can  then  be  read  at  the  vernier  of  the  latitude 
arc. 

The  same  method  may  be  pursued  by  night  to  determine  the  lati- 
tude by  an  observation  on  any  celestial  object  within  *1;he  zodiac, 
viewed  through  the  equatorial  sights.  In  making  these  observa- 
tions, it  will  sometimes  be  necessary  for  an  assistant  to  hold  a  lighted 
candle  a  little  behind  and  above  the  head  of  the  observer,  in  such  a 
manner  that  the  equatorial  sights  can  be  seen;  but  not  so  bright  aa 
to  obscure  the  star. 

LATITUDE  BY  THE  POLE-STAR. 

It  should  be  remarked,  that  the  latitude  given  by  an  observation 
on  any  heavenly  body  within  the  zodiac,  is  read  direct  on  the  lati- 
tude arc ;  but  when  the  latitude  arc  is  turned  to  the  north  for  an 
observation  on  the  pole-star,  or  some  other  star  near  the  pole,  the 
latitude  arc  will  read  the  co-latitude  of  the  station ;  it  must,  there- 
fore, be  subtracted  from  90°  to  obtain  the  true  latitude.  In  these 
latter  observations,  the  polar  distance  of  the  star  must  be  set  off  on 
the  declination  arc  instead  of  its  declination,  and  if  the  upper  meri- 
dian passage  of  the  star  be  observed,  the  decimation  arc  must  be 
turned  toward  it ;  but,  if  the  lower  meridian  passage  of  the  star  bs 
observed,  the  declination  arc  must  be  turned  from  the  star. 

See 'sixth  adjustment  to  find  the  index  error  of  the  latitude  arc.

To  find  the  time  of  the  meridian  passages  of  flie  pole  star,  add

TO  FIND  THE  TRUE  MERIDIAN,  AND  HORIZONTAL  ANGLES 
FROM  IT;  ALSO,  THE  VARIATION  OF  THE  NEEDLE. 

Clamp  the  sight  of  the  compass  at  0  or  zero,  and  adjust  the  lati- 
tude arc  to  the  latitude  of  the  place;  also,  set  off  the  sun's  decima- 
tion for  the  time  of  day,  allowing  for  index  error,  if  any,  and  the 
sun's  meridional  refraction;  then  bring  the  sights  of  the  compass 
approximately  into  the  meridian  by  the  needle,  and  the  solar  lenses 
into  the  direction  of  the  sun ;  if  the  sun's  image  does  not  fall  between 
the  equatorial  lines,  turn  the  instrument  horizontally,  and  the  re- 
volving limb  v.  on  its  axis,  in  a  manner  to  bring  the  sun's  image  be- 
tween the  equatorial  lines,  allowing  for  refraction,  if  required ;  then 
the  compass  sights  will  be  in  the  true  meridian.  Now  if  the  needle 
q.  be  lowered  on  to  its  pivot  by  the  lever  r.,  its  variation  from  the 
true  meridian  can  be  read,  and  set  off  on  the  arc  for  that  purpose ; 
the  tangent  screw  of  the  vernier  limb  is  seen  at  k.  and  d.  (See 
Plate  1.) 

To  set  the  sights  of  the  compass  to  any  other  course  or  angle  from 
the  meridian  it  is  only  necessary  to  unclamp  the  under  plate  from 
the  upper,  and  turn  the  sights  to  the  course  required,  the  angle  of 
which  can  be  read  at  the  verniers  d.  d. 

Observations  for  the  same  purpose  can  be  made  in  the  night,  on 
any  celestial  object  within  the  zodiac,  by  the  use  of  the  equatorial 
sights,  instead  of  the  lenses;  and  by  observing  two  stars,  one  east, 

C 


26  THE   SOLAR    COMPASS. 

and  the  other  west  of  the  meridian,  the  variation  of  the  needle,  or 
the  course  of  a  line,  may  be  more  accurately  defined. 

ZENITH  DISTANCE  AND  ALTITUDE. 

Clamp  the  compass  sights  to  90°,  or  for  an  E.  and  W.  course,  also, 
set  off  on  the  declination  arc  23  degrees,  and  bring  the  revolving 
limb  v  to  zero  or  noon  on  the  hour  arc.  Then  by  turning  t  he  in- 
strument horizontally  on  its  lower  axis,  bring  the  solar  lenses  and 
equatorial  sights  into  the  direction  of  the  sun  or  star  to  be  observed, 
and  raise  or  lower  the  latitude  arc  as  the  case  requires,  until  the 
sun's  image  falls  between  the  equatorial  lines,  or  the  star  is  seen 
through  the  equatorial  sights.  If  the  observation  be  made  with 
the  declination  arc  turned  from  the  object,  23  degrees  must  be 
added  to  the  reading  of  the  latitude  arc,  to  obtain  the  zenith  distance 
of  the  object  observed;  but  if  the  declination  arc  is  turned  toward 
the  object,  23  degrees  must  be  subtracted  from  the  reading  of  the 
latitude  arc,  to  obtain  the  zenith  distance. 

If  the  zenith  distance  be  subtracted  from  90  degrees,  the  altitude 
of  the  object  will  be  had. 

TIME  OF  DAY  BY  THE  SUN. 

After  an  observation  is  made  to  determine  the  variation  of  the 
needle,  or  the  course  of  a  line  by  the  sun,  bring  the  revolving  limb 
to  one  division  on  the  hour  arc  in  advance  of  the  sun,  then  observe 
the  movement  of  the  sun's  image  to  the  instant  it  arrives  between 
the  hour  lines,-  and  correct  for  index  error  of  the  hour  arc,  and  the 
effects  of  refraction,  and  the  hour  angle  from  the  meridian  at  that 
time,  expressed  in  degrees  will  be  had,  which  may  be  converted 
into  time  by  allowing  15  degrees  for  an  hour,  and  for  each  degree 
four  minutes  of  time.  If  mean  time  is  required,  add  or  subtract 
the  equation  of  time  according  to  its  precept,  and  mean  time  will  be 
had. 

DIURNAL  VARIATION  OP  THE  NEEDLE. 

It  has  been  found  by  numerous  observations,  that  the  diurnal  va- 
riation of  the  needle  is  more  in  summer  than  in  winter  months,  and 
the  amount  of  these  aberrations  is  more  or  less  on  different  days  of 
the  same  season  of  the  year,  and  is  probably  caused  by  heat  and  cold. 

But  the  order  in  which  these  diurnal  changes  take  place,  can  be 
a  little  more  clearly  denned.  The  north  end  of  the  needle  will  ar-

rive  at  its  most  easterly  declination  between  one  and  two  hours  after 
sunrise.  It  will  soon  after  gradually  decline  westerly  until  one  or 
two  o'clock,  P.  M.,  soon  after  which  it  will  decline  eastward,  and 
at  sunset  it  will  have  returned  half  way  back  to  where  it  was  in  the 
morning.  Its  daily  movement  may  be  better  understood  by  an  ex- 
amination of  the  following  table : —

28  THE   SOLAR   COMPASS. 

It  will  be  seen  that  the  average  variation  for  eighteen  days 
at  5h.,  80m.,  A.  M.,  is  1°  39'  50",  E. 
at  1  h.,  OOrn.,  P.  M.,  is  1°  25'  37",  E. 
at  6h.,  30m.,  P.  M.,  is  1°  33'  23",  E. 

The  difference  of  these  numbers  gives  the  diurnal  variation  aa 
follows: — 

Between  morning  and  evening — 6'  27", 
Between  morning  and  noon — 14'  13", 
Between  noon  and  evening — 7'  46". 

From  these  facts  it  may  be  seen,  that  the  variation  of  the  needle, 
as  found  at  one  time,  cannot  be  safely  relied  upon  in  running  lines 
at  any  length  of  time  subsequently.  Hence  the  importance  of  find- 
ing its  variation  at  the  time  the  line  is  being  run. 

To  guard  against  errors  occurring  on  account  of  the  variation, 
the  surveyor  should  at  the  end  of  each  line,  or  at  the  point  where 
the  variation  of  the  needle  is  found,  for  the  purpose  of  running  a 
line  from  it  at  some  future  time,  take  the  bearing  of  some  distant 
object,  and  make  a  note  of  the  same.  On  resuming  the  work,  if  the 
sun  should  be  obscured  by  clouds  so  as  to  prevent  finding  the  varia- 
tion of  the  needle,  he  can  observe  the  course  of  the  same  object  again, 
and  the  difference  in  its  course,  if  any,  is  the  change  of  variation,  and 
must  be  allowed  for  to  correct  the  variation  previously  determined. 
Local  attraction,  also,  so  frequently  changes  the  direction  of  the 
needle,  that  the  surveyor  cannot  safely  extend  his  line  far  without 
an  observation  to  find  its  variation;  and  it  will  be  frequently  found 
that  a  little  delay  for  this  purpose,  will  more  than  compensate  for 
all  the  supposed  advantages  of  running  the  line  without  it. 

TO  FIND  THE  MERIDIAN  PASSAGE  OF  A  FIXED  STAR, 
AND  ITS  HOUR  ANGLE  AT  ANY  HOUR  OF  THE  DAY. 
Subtract  the  sun's  Right  Ascension  for  the  day  and  hour  of  obser- 
vation, from  the  star's  -Right  Ascension,  borrowing  24  hours  for  the 
latter  when  necessary,  and  the  difference  will  give  the  star's  meri- 
dian passage  in  solar  time;  if  mean  time  be  required,  add  to  or  sut- 
tract  from  the  solar  time,  the  equation  of  time,  according  to  its 
precept,  and  the  meridian  passage  of  the  star  will  be  given  suffi- 
ciently near  for  that  purpose.  Then,  if  the  hour  of  observation, 
(astronomical  time)  can  be  subtracted  from  the  time  of  the  star's 
meridian  passage,  the  star's  hour  angle,  east  of  the  meridian  will  be 


THE   EFFECT   OF  REFRACTION,   ETC.  29 

given;  but  ijf  the  meridian  passage  of  the  star  be  subtracted  from  the 
hour  of  observation,  it  will  give  its  hour  angle,  west  of  the  meridian 
And  thus  it  may  be  determined  what  stars  are  most  favourably  si* 
tuated,  for  the  purpose  of  finding  the  variation  of  the  needle,  at  any 
time  of  night. 

If  any  one  of  the  fixed  stars  named  in  the  preceding  table  are 
not  truly  known  to  the  observer  by  the  geography  of  the  heavens, 
it  is  necessary  to  find  the  time  of  meridian  passage  in  order  to  know 
the  star's  hour  angle  at  the  time  of  the  proposed  observation. 

This  being  known,  set  the  instrument  to  the  star's  declination 
and  the  equatorial  sights  to  the  hour  angle  of  the  star,  on  the  hour 
arj,  then  bring  the  sights  of  the  compass  into  the  meridian  as  near 
as  may  be  by  the  needle ;  the  equatorial  sights  will  then  direct  the 
eye,  nearly,  to  the  star  sought  for,  and  by  a  little  movement  of  the 
Lusty  ^ment  horizontally  on  its  lower  axis,  bring  the  line  of  sight  to 
bea9  lirectly  on  the  star,  and  the  observation  is  complete. 

TITS   EFFECT  OF   REFRACTION  AND   PARALLAX  IN  THE 
USE  OF  THE  SOLAR  COMPASS  EXPLAINED. 

The  equatorial  and  hour  lines  of  the  solar  compass  will  vary  their 
angles  from  the  horizon,  as  the  object  observed  by  the  instrument 
recedes  from,  or  approaches  to  the  meridian  of  the  observer ;  and 
when  at  90°,  or  six  hours  from  the  meridian,  the  equatorial  lines 
will  have  an  angle  to  the  horizon,  equal  to  the  co-latitude,  and  the 
hour  lines  equal  to  the  latitude  of  the  place  of  observation.  Now  if 
the  equatorial  lines  were  at  all  times  in  a  vertical  plane,  passing 
through  the  centre  of  the  celestial  object,  refraction  would  not  pro- 
duce any  effect  in  the  course  of  lines  run  with  the  solar  compass ; 
but  as  they  will  have  an  angle,  as  above  stated,  at  different  hours  of 
the  day,  a  proportion  of  the  whole  amount  of  refraction,  according 
to  the  angle,  must  be  allowed  for,  when  large  enough  to  produce  a 
sensible  effect  in  the  course  of  the  lines.  The  equatorial  lines  are 
parallel  to  the  horizon  when  observing  a  celestial  object  on  the  me- 
ridian; therefore,  the  whole  amount  of  the  meridional  refraction 
must  be  allowed  for,  in  setting  off  its  declination.  The  hour  lines 
are  only  affected  by  the  whole  amount  of  the  refraction,  or  parallax, 
when  on  the  equator,  or  latitude  0°. 

The  effect  of  parallax  of  the  sun  and  large  planets,  is  too  small  to 
be  regarded,  except  in  the  most  refined  observations.  But  the  pa- 
C* 


30  THE    SOLAR    COM  PASS. 

rallax  of  the  moon  is  too  large  to  be  neglected  in  any ;  for  this  rea 
son,  a  tab'.e  of  refraction  in  altitude  is  given  in  this  work. 

Refraction  does  not  decrease  in  regular  proportion  to  the  altitude 
of  the  object,  When  a  celestial  object  is  in  the  zenith,  it  has  no 
refraction  or  parallax ;  but  when  it  is  in  the  horizon,  its  refraction 
is  33'  51/x,  and  at  an  altitude  of  45°  about  one  minute,  (more  ex- 
actly 58X/;)  the  natural  co-tangent  of  the  altitude  of  a  heavenly 
body,  express  nearly  its  refraction. 

For  the  purpose  of  determining  with  facility  the  whole  amount  of 
refraction  in  altitude  of  a  celestial  object,  the  compass  sights  have 
lines  drawn  across  them  at  various  distances  from  the  top ;  at  each 
of  these  lines  are  figures,  which  indicate,  in  minutes  of  a  degree,  the 
amount  of  refraction  in  altitude  of  a  celestial  object,  as  seen  from 
each  line  in  range  with  the  top  of  the  other  sight. 

From  the  amount  of  refraction  thus  found,  subtract  the  meridional 
refraction,  then  the  following  table  will  give  the  proportion  of  the 
remainder,  expressed  in  hundredths,  to  be  added  to  its  declination, 
when  the  latitude  is  of  the  same  name ;  or  subtracted  from  it,  when 
of  a  contrary  name,  from  one  to  six  hours  in  time,  east  and  west  of 
the  meridian;  also,  the  proportion  of  the  whole  amount  of  the  sun's 
refraction,  to  be  subtracted  in  time  from  his  hour  arc,  in  the  fore- 
noon, and  added  to  it  in  the  afternoon,  to  obtain  the  true  apparent 
time.  This  table  will  also  be  useful  in  observations  on  the  Moon ; 
for  the  same  proportion  of  the  moon's  parallax  in  altitude,  must  be 
allowed  for  on  the  declination  arc,  in  a  reversed  order  from  that  of 
refraction;  in  other  words,  the  same  proportion  of  the  moon's  pa- 
rallax in  altitude,  corrected  for  refraction,  (see  table  for  that  pur- 
pose) must  be  subtracted  from  her  declination,  when  the  latitude  is 
of  the  same  name,  and  added  to  it,  when  of  a  contrary  name. 

For  the  purpose  of  making  corrections  for  refraction  expeditiously, 
while  running  lines  by  the  sun,  there  are  three  lines  drawn  below 
the  equatorial  lines,  57  apart,  by  which  to  estimate  the  proportion 
of  refraction  to  be  allowed,  by  bringing  the  lower  limb  of  the  sun's 
image  the  number  of  minutes  below  the  lower  equatorial  line  on  the 
silver  plate,  instead  of  setting  it  off  with  the  sun's  declination. 
When  the  surveyor  becomes  familiarly  acquainted  with  making  these 
allowances  for  refraction,  in  using  the  solar  compass,  he  will  seldom 
need  to  refer  to  the  tables,  or  to  mathematical  calculations,  to  en- 
able him  to  make  a  proper  allowance  for  refraction  at  all  hours  01

.lie  day,  except  when  the  sun  is  within  5°  of  the  horizon.  But  for 
an  observation  by  night  on  a  star,  its  refraction  should  be  set  oft 
with  its  declination,  in  the  manner  before  stated.

The  correction  for  an  increase  of  altitude  of  one  inch  in  the  Baro- 
meter, or  for  depression  of  one  degree  in  the  Thermometer,  is  to  be 
added  to  the  tabular  refraction ;  but  when  the  Barometer  is  lower 
than  thirty  inches,  or  the  Thermometer  higher  than  47  degrees,  the 
correction  becomes  subtractive. 

When  great  accuracy  is  required,  0-003  inch  should  be  deductel 
from  the  observed  height  of  the  Barometer,  for  each  degree  that  the 
Thermometer  near  it  is  above  fifty  degrees,  and  the  same  quantity 
added  for  an  equal  depression.

MEASURING  LINES. 

In  the  surveys  of  the  United  States  lands  it  is  required,  that  the 
measuring  chain  should  be  two  poles,  or  thirty-three  feet  in  length, 
and  containing  fifty  links,  which  must  be  compared  with,  and  ad- 
justed to  the  length  of  the  standard  chain  in  the  Surveyor  General's 
Office,  and  afterwards  to  be  frequently  compared  with  a  standard 
chain  kept  by  the  surveyor  for  that  purpose.  But  all  the  measure- 
ments, and  calculations,  are  kept,  and  entered  in  the  field  book,  in 
four  pole  chains,  of  one  hundred  links. 

The  surveyor  is  required  to  use  eleven  tally  pins ;  they  should  be 
made  of  steel,  and  not  more  than  about  one  foot  in  length,  and  largs 
enough  near  the  points,  to  cause  them  to  drop  perpendicularly ;  at 


MEASURING    LINES.  33 

the  top  end  of  each  pin,  a  loop  or  eye  should  be  made,  in  which  a 
piece  of  red  cloth  may  be  fixed,  that  they  may  be  more  readily 
found,  when  stuck  among  weeds,  grass,  £c. 

In  all  measurements  the  level  or  horizontal  length  is  to  be  taken; 
for  this  purpose,  in  ascending  hills,  banks,  £c.,  the  chain-men  must 
let  down  one  end  of  the  chain  to  the  ground,  and  raise  the  other  end 
to  a  level  therewith,  at  the  elevated  end  of  which  a  tally  pin  should 
be  plumbed  and  let  fall,  to  ascertain  the  spot  for  setting  it ;  and, 
when  the  surface  of  the  ground  is  very  steep,  it  may  be  necessary 
to  take  £0  much  of  the  length  of  the  chain  as  can  be  raised  to  a  level, 
so  as  to  obtain  the  true  horizontal  measurement. 

In  measuring  lines,  one  of  the  eleven  tally  pins  must  be  set  at  the 
starting-point,  and  when  the  remaining  ten  are  set,  it  is  called  a 
tally  or  out,  (five  chains)  and  the  forward  chain-man  cries  "Tally, 
and  each  chain-man  registers  the  distance  by  slipping  a  thimble  or 
loop  on  a  tally  belt  worn  for  that  purpose.  The  back  chain-man 
then  comes  up,  and  having  counted,  in  the  presence  of  his  fellow, 
the  tally  pins  which  he  had  taken  up,  so  that  both  may  be  assured 
that  none  have  been  lost,  takes  the  forward  end  of  the  chain  and 
proceeds  to  set  them.  Thus  the  chain-men  alternately  change  places, 
each  setting  the  pins  that  he  had  taken  up,  so  that  one  is  forward 
in  all  the  odd,  and  the  other  in  all  the  even  tallies;  which  contri- 
butes to  the  accuracy  of  the  measurement,  facilitates  the  recollection 
of  the  distances  to  notable  objects  on  the  line,  and  renders  a  mis- 
tally  almost  impossible. 

Measurements  with  the  chain  and  tally-pins  are  often  very  im- 
perfectly performed  by  the  chain-men,  and  much  more  error  is  mado 
than  is  generally  supposed.  It  has  been  found  by  many  trials,  with 
as  good  men  as  can  generally  be  obtained,  that  with  two  sets  of  chain- 
men,  instructed  alike  in  the  proper  manner  of  keeping  their  chain 
level  and  straight  on  the  line,  and  of  setting  the  tally-pins  plumb, 
as  well  as  holding  the  ends  of  the  chain  to  them,  a  difference  has 
sometimes  been  made  of  36  links,  and  an  average  difference  of  15 
or  16  links  to  a  mile,  in  common  timbered  land.  But  repeated 
measurements  over  the  same  mile,  by  the  same  chain-men,  and  near 
the  same  time,  will  generally  agree  within  fivo  links ;  yet  after 
several  months'  employment  in  the  field,  a  measurement  of  this  line 
may  not  agree  so  nearly.  Again,  the  same  chain-men  will  make  a 
different  measurement  to  some  extent,  over  swamps,  marshes,  wind-

falls  and  thickets,  when  there  is  snow  on  the  ground  and  when 
there  is  none,  in  cold  and  in  warm  weather,  effecting  a  change  in 
the  length  of  the  chain,  and  by  measuring  fast  or  slow  the  amount 
of  error  to  each  would  be  difficult  to  estimate.  Therefore  the  sur- 
veyor should  keep  a  vigilant  watch  over  his  chain-men,  and  see  that 
their  duties  are  performed  in  the  best  manner,  to  counteract  all 
these  sources  of  error  as  far  as  practicable. 

TELESCOPIC  MEASUREMENT. 

This  method  of  measuring,  when  properly  conducted,  is  more 
uniformly  the  same,  and  therefore  correct,  than  measurements 
made  by  the  chain  by  various  chainmen.  It  is  well  adapted  to 
measure  along  the  shores  of  lakes  and  rivers  where  obstacles  are 
frequently  found  of  a  character  to  prevent  a  good  measurement  with 
a  chain,  also  for  measuring  short  distances  over  streams,  ponds,  &c. 

The  following  arrangement  and  method  of  measuring  with  a  tele- 
scope and  rod  will  be  found  very  convenient  for  meandering  rivers, 
lakes,  &c.  A  good  telescope  must  be  provided,  of  about  16  or  18 
inches  in  length  when  adjusted  for  use,  with  two  parallel  lines  cor- 
rectly set  in  its  principal  focus,  forming  between  them,  in  the  field 
view,  not  less  than  45'  of  a  degree.  This  telescope  is  attached  to 
the  sight  of  the  compass  with  a  suitable  fixture  for  that  purpose, 
when  wanted  for  use.  Provide  a  sliding-rod,  such  as  are  commonly 
used  for  taking  levels  for  canals,  railroads,  &c.,  with  two  targets, 
one  stationary  at  the  top  of  the  rod,  the  other  moveable,  with  a 
vernier  for  the  usual  readings,  on  the  lower  part. 

When  measurements  with  the  telescope  and  rod  are  to  be  made, 
the  telescope  must  be  attached  to  the  compass  sights  and  adjusted 
for  an  observation;  then  measure  four  chains  from  it  very  accu- 
rately, and  place  the  rod  at  that  point,  with  ths  targets  facing  the 
compass,  then  bring  the  upper  line  in  the  telescope  to  bear  correctly 
on  the  upper  target  by  means  of  the  levelling  screws,  and  adjust  the 
moveable  target  to  range  with  the  lower  line,  then  by  observing 
accurately  the  distance  the  targets  are  apart  on  the  rod,  when  they 
measure  the  angle  formed  by  the  parallel  lines  in  the  telescope  at 
the  given  distance  from  the  compass,  the  observer  will  have  data 
from  which  a  table  may  be  readily  constructed  for  all  other  dis* 
tances,  of  which  the  telescope  will  enable  the  observer  to  view  th« 
distance  between  the  targets  accurately.  It  may  conduce  to  tha 


METHODS   FOR   MEASURING   DISTANCES,   ETC.    37 

correctness  of  this  method  of  measuring  to  make  observations  at 
various  distances,  to  test  the  accuracy  of  the  table  thus  formed; 
after  this,  the  surveyor  may  feel  a  confidence  in  the  correctness  ol 
his  measurements  with  the  telescope  and  rod. 

Lines  run  and  measured  by  this  arrangement  along  the  shores  ot 
lakes  and  navigable  streams  are  most  conveniently  and  expeditiously 
done  with  two  skiffs  or  canoes,  or  even  with  two  light  rafts,  with 
the  compass  in  one«and  the  rod  in  the  other,  which  can  be  landed 
at  suitable  points  and  distances  apart  on  their  shores ;  then,  after 
the  bearing  and  distance  between  them  has  been  taken,  the  compass 
can  be  moved,  with  the  skiff  or  canoe,  to  the  position  occupied  by  the 
rod,  and  the  latter  again  stationed  at  the  next  suitable  point,  and 
its  course  and  distance  taken  as  before,  and  so  on  to  the  close  of  the 
survey. 

In  all  observations,  care  should  be  taken  to  hold  the  rod  at  right 
angles  to  the  line  between  it  and  the  compass ;  but  it  is  often  neces- 
sary to  lean  the  rod  at  right  angles  to  this  line,  sometimes  even  to 
a  level  with  the  horizon;  in  all  such  cases,  the  telescope  must  be 
rolled  in  the  y's  to  bring  the  parallel  line  at  right  angles  to  the  rod. 
By  this  method,  the  shores  of  lakes  and  rivers,  however  difficult 
to  be  measured  with  the  chain,  may  be  correctly  meandered  by 
course  and  distance,  without  encountering  the  obstacles  on  shore 
with  the  compass  and  chain. 

To  prevent  confusion  or  mistake  in  the  locality  of  the  different 
stations  and  notable  objects  on  the  land  or  off  the  shore,  a  tempo- 
rary map  should  be  fully  kept  up  with  the  survey,  on  which  each 
object  must  be  represented  in  order  to  furnish  data  for  the  con- 
struction of  a  good  and  correct  map. 

No  surveyor,  however,  should  presume  to  meander  important 
surveys  by  this  method,  except  he  has  previously  made  the  neces- 
sary preparations,  and  has  qualified  himself  by  some  practical 
experience  beforehand.

CONVENIENT  METHODS  FOR  MEASURING  DISTANCES  OVER 

RIVERS,  LAKES,  MIRY-MARSHES,  ETC. ;  WHICH  CANNOT 

BE  MEASURED  DIRECTLY  WITH  THE  CHAIN. 

It  may  be  remarked  here,  that  in  surveying  large  districts  of  new 

country,  many  obstacles  of  this  kind  are  to  be  expected,  and  are  met 

with  sometimes  under  many  difficulties,  such  as  the  direction  and 

swampy  or  thickety  character  of  their  shores,  also,  the  annoyance 

felt  by  the  presence  of  increasing  swarms  of  blood-thirsty  flies  and 

moschetoes,  which  largely  infest  such  shores  in  summer;  hence  the 

importance  of  the  best  management,  and  correct  and  expeditious 

methods  of  passing  such  obstacles. 

The  following  illustrations  will  assist  the  inexperienced  surveyor 
in  the  accomplishment  of  this  object.  They  are  given  on  the  princi- 
ple of  reducing  the  base,  whatever  may  be  its  course  or  courses,  TO

a  right-angled  base  to  the  course  of  the  lino  to  be  measured.  This 
can  be  readily  done  if  care  be  taken  to  run  and  measure  the  base, 
at  such  angles  that  their  latitude  and  departure  can  be  taken  from 
the  traverse  table.

EXAMPLE. 


FIGURE  4. 

In  running  a  line  north,  intersect  the  right  bank  of  .a  river  at  A, 
(course  N.  N.  E.,)  and  erect  an  object,  turn  the  compass  sights  to 
west,  to  an  object  at  B,  and  pass  over  the  river  to  it,  then  run  and 
measure  a  line  north  to  <7,  and  "off-set"  east  into  line  at  D,  the  dis- 
tance between  A  and  D  will  be  equal  to  the  distance  between  B  and 
C.  Or,  if  a  line  be  run  and  measured  from  A,  N.  60°,  E.  until  an 
object  in  line  at  D  bears  N.  30°  W.,  the  distance  A.  D.  will  be  twice 
that  of  A.  JB.,  for  the  reason  that  the  triangle  thus  formed  is  one- 
half  of  an  equilateral  triangle. 

Frequently  off-sets  are  made  in  passing  small  lakes,  bends  of  rivers, 
etc.:  sometimes  the  distances  can  be  advantageously  taken  over 
such  obstacles,  with  the  telescope  and  rod,  (see  article,  Telescopic 
Measurement.)  Also,  it  often  happens  that  a  suitable  angle  can  be 
taken,  and  the  base  to  that  angle  measured  afterwards;  in  such 
eases  the  distance  can  be  taken  from  the  traverse  table ;  but  if  no 
traverse,  or  other  proper  tables  are  at  hand,  the  following  angles, 
on  a  right  angle  base,  and  the  multiplier  to  it,  will  give  the  distance. 
These  may  be  committed  to  memory.

SHORT  METHOD  OF  FINDING  THE  AREA  OF  A 
MULTANGULAR  FIELD. 

EXAMPLE,  SHOWING  HOW  TO  REDUCE  THE  PLOT  OF  A  MULTANGULAR 
FIELD  TO  A  FIELD  OF  EQUAL  AREA  HAVING  ONLY  THREE  OR  FOUR 
SIDES,  BY  WHICH  ITS  CONTENTS  MAY  BE  READILY  FOUND. 

To  reduce  such  a  field  the  only  instruments  required,  after  the 
meanders  are  properly  laid  down,  are  a  good  parallel-rule,*  and  a 
fine  protracting  point. 

In  the  preceding  figure  first  extend  the  base  UN  to  an  indefinite 
length ;  then  placing  the  rule  on  the  angles  1  and  3,  move  it  parallel 
from  the  angles  1  and  3  to  the  angle  2,  and  mark  the  exact  point  of 
intersection  at  A,  on  the  base  EH.  Now  place  the  rule  on  A  and 
the  angle  4,  then  move  it  parallel  to  the  angle  3,  finding  the  point  £ 
on  the  base  E  H\  place  the  rule  on  B  and  the  angle  5,  and  move, 
parallel,  to  the  angle  4,  finding  the  point  G  on  the  base  EH.  Novf 
place  the  rule  on  the  point  (7,  and  the  terminating  point  6  on  the  lin« 
FG,  and  move  the  rule,  parallel,  to  the  angle  5,  finding  the  point 
D  on  the  base  EH,  from  which  point  draw  a  line  to  6,  the  process 
then  being  complete.  The  line  D  6  thus  drawn  leaves  the  same  area 
of  lake  to  the  left,  that  there  is  of  land  to  the  right.

ward to  c  and  so  on  to  the  angle  at  i,  leaving  a  triangle  to  the  right 
of  the  perpendicular.  Proceed  in  like  manner  with  that  portion  of 
the  figure  to  the  left  of  the  perpendicular  line,  throwing  it  into  two 
triangles. 


CROSSING  RIVERS  AND  LAKES. 

In  connexion  with  convenient  methods  of  measuring  distances 
over  lakes  and  rivers,  it  is  proper  to  take  notice  of  the  means  em- 
ployed, by  the  most  experienced  survej'ors,  for  the  transit  of  the 
surveying  party  over  such  waters,  when  fording  them,  or  travelling 
around  their  shores,  is  impracticable,  or  causes  too  much  delay. 

For  this  purpose  floats  or  rafts  made  of  logs,  of  the  most  dry  and 
ouoyant  timber  at  hand  is  used,  and  when  formed  into  a  raft,  its 
length  should  be  about  four  times  its  breadth ;  with  this  proportion 
the  raft  will  steer  better,  and  pass  through  the  water  with  more  ease 
and  expedition,  than  broad  and  short  rafts. 

The  following  is  a  safe  and  expeditious  method  of  constructing 
these  floats: — At  a  convenient  place  lay  two  skids,  at  a  suitable  dis- 
tance apart,  parallel  to  the  shore,  and  near  to  the  water,  place  on 
these  two  logs,  twenty  feet  long  and  one  foot  diameter,  which  are 
to  be  the  outside  logs  of  the  raft,  and  at  about  two  or  three  feet 
from  the  ends  of  these,  make  with  an  axe  a  dovetail  notch  three  or 
four  inches  deep,  and  about  as  wide  on  their  upper  sides ;  then  fit 
into  these  notches  a  cross  piece,  or  tie  of  a  suitable  size,  and  wedge 
them  there  firmly,  so  that  these  logs  will  not  be  separated  on  the 
water;  then  before  or  after  launching  this  into  the  water,  as  con- 
ven^nce  may  suggest,  fill  in  underneath  the  cross  pieces,  between 
the  outside  logs,  with  smaller  timber  of  the  same  length,  and  tie 
them  to  these  pieces,  or  fasten  them  by  means  of  a  dovetail  notch. 
For  crossing  deep  water,  where  poles  cannot  be  used,  paddles,  or 
oars  will  be  needed;  they  can  be  split  out  of  a  log  and  hewn  into  the 
proper  shape  in  a  few  minutes. 

With  the  whole  force  of  the  surveying  party,  it  will  require  frcm 
one  to  two  hours  to  construct  a  raft  of  a  sufficient  size  to  pass  then* 
all  over  a  lake  or  river  at  one  time. 


RUNNING    LINES   WITH    SOLAR    COMPASS.      45 


RUNNING  LINES  WITH  THE  SOLAK  COMPASS. 

In  commencing  a  survey  where  the  latitude,  as  given  by  the  in- 
strument with  which  the  survey  is  to  be  made,  is  unknown,  the  sur- 
veyor should  first  determine  the  latitude  of  his  commencing  point. 
He  should  remember,  that  in  running  any  other  than  an  east  and 
west  line,  he  is  continually  changing  his  latitude,  so  that  every 
ninety-two  chains  and  thirty  links,  of  northing,  or  southing,  will 
change  his  latitude  one  minute  of  a  degree,  or  5'  12X/  for  six  miles, 
and  a  corresponding  change  of  latitude  must  be  set  off  on  the  lati- 
tude arc.  During  the  progress  of  a  large  survey,  the  surveyor 
should  determine  his  latitude  daily,  if  practicable,  by  the  meridian 
passage  of  the  sun,  to  test  the  correctness  of  the  adjustments  of  the 
latitude  and  declination  arcs. 

It  is  equally  important  that  the  sun's  declination  be  truly  set  off 
on  the  declination  arc,  for  the  time  and  longitude  of  the  station,  as 
it  is  that  the  latitude  arc  be  truly  adjusted  to  the  latitude  of  the 
place  of  observation. 

The  following  method  of  preparing  the  sun's  declination,  as  taken 
from  the  Nautical  Almanac,  for  daily  use,  in  any  longitude,  will  be 
found  useful  in  practice:

The  calculations  for  the  sun's  declination  for  each  hour  of  the 
day  can  be  made  after  the  preceding  forms,  on  blank  leaves  placed 
in  the  field  book,  where  they  would  be  required  through  the  day. 

In  the  following  table  the  hourly  difference  of  the  sun's  declina- 
tion, as  given  for  the  day,  in  the  Nautical  Almanac,  will  be  found  to 
the  nearest  second  in  the  left  hand  column,  and  the  change  of  de- 
clination for  any  number  of  hours  to  twelve,  will  be  found  against 
it,  under  the  hour  at  the  head  of  the  columns. 
•  This  table  is  useful  when  the  sun's  declination  is  required  for  any 
number  of  hours  up  to  twelve,  before  or  in  advance  of  Greenwich 
noon. 


Suppose  the  sun's  declination  is  required  for  September  6,  1854, 
at  2  h.  P.  M.,  in  longitude  120°  W.,  or  8h.  in  time  W.  of  Greenwich, 
then  84-2=10  hours.  The  sun's  declination  at  Greenwich  noon  id 
6°  28'  52"  N. ;  hourly  difference  56",  against  this,  in  the  above 
table,  and  under  10  hours,  we  find  9'  20",  which  subtract  from 
6°  28'  52"=:60  19-'  32"  for  the  sun's  declination  at  the  time  and 
place  required. 

*  The  hourly  difference  of  the  sun's  declination  must  be  added  when  his  de« 
clmation  is  increasing,  and  subtracted  when  it  is  decreasing';  and  the  meridional 
refraction  must  be  added  to  the  declination  when  the  latitude  is  of  the  sam« 
name,  and  subtracted  when  of  a  contrary  name.  See  method  of  finding  Meri- 
dional Refraction.

4S  THE    SOLAR    COMPASS. 

Observations  with  the  solar  compass  for  the  purpose  of  running 
lines,  or  to  determine  the  variation  of  the  needle,  should  not  be  made 
when  the  sun  or  other  celestial  object  is  nearer  than  8°,  or  thirty- 
two  minutes  of  time  from  the  meridian :  nearer  than  this,  the  obser- 
vations may  not  give  the  course  required  sufficiently  correct  for  the 
ordinary  purpose  of  running  lines. 

The  best  part  of  the  year  for  running  lines  with  the  solar  compass 
is  the  summer  season,  or  when  the  latitude  and  the  declination  of 
the  sun  are  both  of  the  same  name.  During  this  portion  of  the  yeai 
there  is  usually  the  most  fair  weather  for  work  of  this  kind,  and 
the  sun's  altitude  being  generally  higher  through  most  of  the  day, 
affords  more  frequent  opportunities  in  the  forest  to  adjust  the  in- 
strument by  the  sun,  to  the  course  of  the  line.  There  are,  also, 
more  hours  of  the  day  in  which  the  solar  compass  can  be  used;  the 
advantages  of  this  will  be  fully  realized  when  running  lines  in  thickly 
timbered  land,  or  in  hilly  or  mountainous  districts,  when  their  sum- 
mits intervene  between  the  instrument  and  the  sun,  until  a  late  hour 
in  the  morning  and  early  in  the  afternoon. 

From  the  principles  already  given  in  regard  to  the  use  of  the  solar 
compass,  it  will  be  perceived,  that  it  requires  more  skill  to  use  it 
with  facility,  than  it  does  to  use  the  magnetic  compass ;  therefore, 
the  surveyor  should  acquire  this  skill,  before  entering  upon  any  im- 
portant survey. 

More  line  can  be  run  with  the  solar  compass  in  a  day,  than  with 
the  magnetic  compass  in  the  same  time,  if  both  instruments  are  pro- 
perly used;  for  the  reason  that  it  requires  less  time  to  adjust  the 
solar  compass  to  the  course  by  the  sun,  than  it  does  the  magnetic 
compass  by  the  needle. 

Much  experience  has  established  the  fact,  that  a  continual  line 
can  be  run  independently  of  the  needle,  through  heavy  timbered 
land,  without  cutting  away  any  timber,  except  lopping  a  bush  oc- 
casionally, between  the  instrument  and  the  sun.  -Therefore,  lines 
can  be  correctly  run  through  any  mineral  region  or  other  country, 
however  great  the  local  attractions  or  variations  may  be  on  the 
magnetic  needle,  with  an  accuracy  not  attainable  with  the  magnetic 
compass.  In  making  the  survey  of  new  districts  of  country,  espe- 
cially where  there  is  considerable  local  attraction,  it  is  important  to 
del  ermine  the  variation  of  the  needle  frequently,  and  make  a  record 
of  the  same  for  future  reference. 


CORRECTION    FOR    RANDOM    LINES.  49 

During  the  surveys  of  the  mineral  region  of  Lake  Superior,  it  was 
Discovered  that  all  mineral  veins  in  that  country  had  an  influence, 
more  or  less,  on  the  direction  of  the  magnetic  needle,  its  North  end 
being  generally  attracted  towards  the  metallic  vein.  These  indica- 
tions led  (and  no  doubt  will  to  a  greater  extent  in  future)  to  the 
discovery  of  mineral  veins  of  various  kinds  in  that  and  other  regions; 
but  the  influence  of  metallic  deposits  on  the  magnetic  needle,  ac- 
cording to  their  various  qualities,  courses,  distances,  depths,  &c., 
from  the  instrument,  are  as  yet  imperfectly  understood. 

It  is  to  be  hoped  that  this  subject  wilt  receive,  in  future,  that  at- 
tention which  its  importance  requires. 

These  aberrations  in  proximity  to  metallic  deposits,  suggest  to  the 
mind  that  they  may  be  caused  by  galvanic  currents,  which  circulate 
around  the  earth,  and  become  deflected  out  of  their  general  course 
by  the  metallic  veins  being  a  better  conductor  than  the  surround- 
ing medium. 

Galvanic  currents  conducted  by  any  metallic  substance  always  in- 
fluence the  direction  of  the  magnetic  needle,  and  incline  it  toward 
a  right  angle  to  its  course ;  metallic  deposits  may  also,  in  connexion 
with  the  various  rocks  and  other  substances  in  which  they  are  im- 
mediately enclosed,  form  in  themselves,  local  galvanic  batteries,  of 
greater  galvanic  intensity  than  is  generally  circulating  in  their  vi- 
cinity, and  thus  diffuse  an  influence  around  them  at  considerable 
distances. 

If  these  suggestions  are  correct,  they  seem  to  point  to  metallic 
deposits,  in  connexion  with  other  substances  in  which  they  are  en- 
closed, as  the  producing  cause  of  the  galvanic  currents  which  cir- 
culate continually  around  the  earth,  nearly  at  right  angles  to  ita 
axis. 

CONVENIENT  RULES  FOR  CORRECTING  THE  COURSE  OF 
RANDOM  LINES,  WHEN  THE  CORRECTION  DOES  NOT 
EXCEED  200  LINKS  TO  EACH  MILE. 

Rule  for  half  a  mile,  or  forty  chains. 

From  the  number  of  links  to  be  corrected  in  that  distance,  sub- 
tract one-seventh ;  the  difference  will  be  the  number  of  minutes  of  • 
degree  required  for  the  correction  of  the  course.

50  THE   SOLAR   COMPASS. 

EXAMPLE. 

Number  of  links  to  be  corrected,  42 — 6=36/  answer. 

Rule  for  one  mile,  or  eighty  chains. 

From  half  of  the  number  of  links  to  be  corrected  in  that  distance, 
jubtract  one  seventh ;  the  difference  will  be  the  number  of  minutes 
of  a  degree  required  for  the  correction  of  the  course. 

EXAMPLE. 
Number  of  links  to  be  corrected,  70~-2=35 — 5=30/  answer. 

Rule  for  three  miles. 

Divide  the  whole  number  of  links  to  be  corrected  by  seven ;  the 
quotient  will  be  the  number  of  minutes  of  a  degree  required  for  the 
correction  of  the  course. 

EXAMPLE. 

Number  of  links  to  be  corrected,  297  -~ 7=42 ^  answer 

Rule  for  six  miles. 

Divide  one  half  of  the  number  of  links  to  be  corrected  by  seven ; 
the  quotient  will  be  the  number  of  minutes  required  for  the  cor- 
rection of  the  course. 

EXAMPLE. 

Number  of  links  to  be  corrected,  370  -r-  2  =  185  ^7  =  26|/  ans.* 

The  distances  given  for  corrections,  in  the  above  examples,  are 
those  for  which  corrections  are  generally  made  in  the  surveys  of  the 
public  lands,  and  the  calculation  for  the  course  of  the  corrected  line, 
can  generally  be  mentally  made  by  the  surveyor,  while  he  is  occu- 
pied in  adjusting  his  instrument. 

For  other  distances,  when  the  correction  does  not  exceed  1°  45/, 
divide  the  distance  run,  by  the  number  of  links  to  be  corrected  in 
the  length  of  the  line;  the  quotient  will  be  the  natural  co-tangent  of 
the  correction  to  be  applied  to  the  random  course. 

In  the  following  table,  the  angle  of  correction  is  given  in  the  first 
column  from  \f  to  1°  4(K;  and  against  each  angle  the  departure  is 
given  for  distances  one,  forty,  eighty,  and  two  hundred  and  forty  chains, 
or  three  miles.  These  distances  may  b«  reckoned  as  tens,  hundreds, 
thousands,  if  the  position  of  the  decimal  point  in  each  departure  be 
changed  accordingly. 

The  departure  under  distance  one  chain  is  of  course  the  natural

sine  of  the  angle ;  therefore,  if  it  be  multiplied  by  the  distance  run 
on  any  angle,  the  product  is  the  departure.

TABLE  OF  LATITUDES  AND  LONGITUDES. 

In  the  use  of  the  Solar  Compass,  it  is  necessary  to  know  approxi- 
mately at  least,  the  Longitude  of  the  place  where  the  instrument  is 
used,  for  the  purpose  of  taking  out  of  the  Nautical  Almanac,  the  Sun's 
declination,  &c.,  and  reducing  them  to  a  time,  and  Longitude  of  the 
place  of  observation. 

For  this  purpose,  the  following  tabular  statement  of  the  latitude, 
and  longitude  from  the  meridian  of  Greenwich,  of  some  of  the  most 
Important  places,  in  North  America,  are  given.

A  degree  of  longitude  at  the  eqxiator  =s=  69-163  statute  miles. 
A  second  of  time  at  the  equator          ==  1521-6  feet. 

RUNNING  PARALLELS  OF  LATITUDE. 

Parallels  of  latitude  are  curved  lines,  and  they  increase  in  curva- 
ture from  the  equator  to  the  poles,  and  cross  all  meridians  at  right 
angles.  All  lines  run  at  any  angle  from  the  meridian,  by  courses 
taken  at  short  intervals,  partake  more  or  less  (according  to  the  angle) 
of  the  curvature  of  parallels  of  latitude. 

When  the  compass  is  set  to  a  true  east  and  west  course,  in  any 
latitude,  the  line  of  sight  is  at  right  angles  to  the  meridian,  and  in 
consequence  of  the  spheroidical  figure  of  the  earth,  which  causes  tho 
curvature  of  the  parallels  of  latitude,  this  line  of  sight  will  converge 


RUNNING  PARALLELS   OF  LATITUDE.  55 

oc  the  equator.  Some  correction  is  therefore  due  to  each  course 
taken  between  stations,  to  keep  the  line  on  the  same  parallel  of  la- 
titude. This  correction,  however,  is  too  small  to  make  any  material 
error  in  tracing  the  parallel,  if  the  stations  are  not  more  than  30//r 
of  longitude  apart;  but  if  larger  than  this,  the  convergency  on  the 
equator  should  be  computed  for  the  distance,  and  allowed  on  the 
side  towards  the  pole.  But  a  more  convenient  and  practical  method 
of  running  parallels  of  latitude,  or  lines  at  any  angle  from  the  meri- 
dian, is  to  back  sight  on  each  forward  sight,  and  take  half  the  dif- 
ference between  their  courses,  when  large  enough  to  be  perceptible. 
Thus,  the  forward  and  back  sights,  give  double  the  amount  of  curva- 
ture between  the  two  stations,  the  one  half  of  which  must  be  set  off 
at  the  end  of  the  forward  sight  toward  the  pole,  to  keep  the  line  on 
the  same  parallel  of  latitude.  Any  unusual  difference  between  two 
equal  stations,  must  be  re-examined,  and  errors  corrected  if  any,  as 
the  line  advances. 

A  line  run  west  six  miles,  or  more,  with  long  stations  between 
sights,  cannot  be  retraced  by  running  east  in  the  same  maDner,  for 
the  east  line  will  fall  towards  the  equator;  therefore  attention  should 
be  given  to  this  subject  in  running  the  east  and  west  lines  of  the 
public  lands,  when  long  distances  are  taken  between  stations  over 
water,  prairies,  or  open  lands. 

When  running  a  parallel  of  latitude,  if  an  object  be  observed  due 
east  or  west  from  any  station,  the  correction  of  the  course  to  touch 
the  same  parallel  on  the  meridian  of  the  object,  is  equal  to  one  half 
of  the  angle  of  convergency  between  the  two  meridians,  which  pass 
through  the  station  and  the  object. 

The  following  table  will  show  the  convergency  of  six  miles  apart  on 
the  parallel  of  each  degre.e  of  latitude,  and  «&  miles  from  them,  to- 
wards the  poles  of  the  earth.

EXPLANATION  AND  USE  OF  THE  ABOVE  TABLE. 

To  find  the  convergency  and  angle  for  the  fractional  parts  of  each 
degree  of  latitude,  increase  the  convergency  and  angle,  in  proportion 
to  the  fractional  part  required.  The  convergency  of  equal  lengths  of 
meridians  with  same  latitude  are  in  proportion  to  their  distance 
apart. 

The  convergency  between  any  two  meridians,  whose  lengths  are 
equal  to  their  mean  distance  apart,  is  in  proportion  to  the  square 
cf  the  distance  given  in  the  table  (six  miles)  to  the  square  of  the 
length  required. 

EXAMPLE. 

Suppose  it  is  required  to  find  the  convergency  of  two  meridians 
three  miles  in  length  and  three  miles  apart,  in  latitude  42°  (62) : 
65.4  : :  32  :  16.35  links. 

Suppose  a  station  in  latitude  42°  N.  an  object  is  observed  due 
east  eight  miles  distant;  how  far  north  of  the  object  is  the  same  pa- 
rallel of  latitude,  of  the  station  from  which  the  observation  is  made  ? 
Proceed  as  in  the  above  example.  36:  65.  4:  :64: 116.  27.  One  half  of 
which  is  58,14  links  nearly,  answer.  (See  rule  preceding  the  above 
table. )  If  the  angle  be  required  that  would  touch  the  same  parallel 


AMPLITUDE   OF   CELESTIAL   OBJECTS.          57 

north  of  the  object,  it  will  be  given  by  the  following  proportion;  6 :  4/ 
41" : :  8 :  G'  14".     One  half  of  which  is  8'  1"  or  N.  89°  56'  53"  E.* 

CONVERGENCY  OF  MERIDIANS. 

RULE. — As  the  cosine  of  any  given  latitude  is  to  a  given  distance 
of  longitude,  in  that  latitude,  so  is  the  cosine  of  any  other  latitude, 
to  the  distance  of  a  corresponding  longitude;  the  difference  of  these 
numbers  will  be  the  convergency. 

EXAMPLE. 

Required  the  convergency  of  two  range  lines  that  are  6  miles  or 
480  chains  apart,  in  latitude  42°  30'  north,  and  extending  north  ten 
townships,  or  to  latitude  43°  21'  48". 

As  cosine  of  lat.  42°  30'  =  9.867631 

:  Longitude  480  chains,  =  2.681241 

: :  Cosine  of  lat.  43°  21',  48"    =  9.861543

TO  RUN  A  LINE  PARALLEL  TO  A  GIVEN  MERIDIAN,  AT  ANY  DISTANCE 
EAST  OR  WEST  OF  IT. 

Find  the  angle  of  convergency  between  the  meridians  for  the  dis- 
tance required,  then  run  the  line  at  the  angle  thus  found,  east  or 
west  of  the  meridian  as  the  case  requires. 

AMPLITUDE  OF  CELESTIAL  OBJECTS. 

All  heavenly  bodies  will  rise  and  set  to  the  north,  or  to  the  south 
of  the  east  and  west  points  of  the  horizon,  as  their  declination  may 
be  north  or  south. 

In  consequence  of  the  horizontal  refraction  of  celestial  objects, 
the  proper  time  of  taking  their  amplitude  is  when  their  centers  ap^ 
pear  about  33'  above  the  horizon. 

TO  FIND  THE  AMPLITUDE. 

To  the  Log,  secant  of  the  latitude  (rejecting  its  index,)  add  the 
Log-sine  of  the  sun's  or  star's  declination ;  the  sum  will  be  the  Log*

PROBLEMS. 

TO  FIND  THE  TIME  OF  THE  SUN  RISING  OR  SETTING. 

RULE. — To  the  tangent  of  the  latitude,  add  the  tangent  of  the 
sun's  or  star's  declination,  and  subtract  radius  from  their  sum ;  the 
remainder  is  the  cosine  of  the  semi-diurnal  arc,  when  the  latitude 
and  decimation  are  of  different  names ;  and  of  the  semi-nocturnal 
arc,  when  both  are  of  the  same  name. 

EXAMPLE. 

Sun's  decl.  18°  20'  Tangent  =  9.520305

SERVING A  CELESTIAL  OBJECT,  AT  ANY  HOUR  ANGLE  FROM  THB 
MERIDIAN. 

RULE. — As  radius  is  to  the  cosine  of  the  latitude,  so  is  the  sine  of 
the  hour  angle  of  the  celestial  object,  to  the  sine  of  the  angle  of  the 
equatorial  lines  with  the  horizon. 

EXAMPLE. 

As  radius,  10.000000

*  To  perform  this  operation  accurately,  two  persons  should  take  contemporary 
observations  with  two  barometers  and  thermometers,  the  one  at  the  bottom  cf  the 
hill,  and  the  other  at  the  top. 

I 


62  THE  BAROMETER. 


ri.  —  The  difference  between  the  two  barometers  at  the  bottom 
and  top  of  the  mountain,  multiplied  by  the  height  of  the  barometer 
at  the  bottom  of  the  mountain;  and  that  product  by  the  tabular  dif- 
ference corresponding  to  the  mean  of  the  thermometers,  and  divided 
by  the  mean  between  the  readings  of  the  barometers,  will  equal  the 
amount  of  elevation  in  feet. 

EXAMPLE. 

Suppose  the  barometer  at  the  bottom  of  the  mountain  to  stand  at 
30  inches,  thermometer  60°;  and  the  barometer  at  the  top  26.36 
inches,  thermometer  46P;  required  the  height  of  the  mountain. 

As  per  rule  the  mean  of  the  two  barometers  =  28.18  inches,  their 
difference  =  3.64  inches;  and  the  mean  of  the  two  thermometers  = 
53°.  The  number  corresponding  to  53°  in  the  table  is  913.0,  hence 
(3,64  X  30  x  913.0)  -i-  28.18  =  3537.92  +.  The  height  of  the 
mountain. 

The  following  are  extracts  from  the  remarks  of  the  late  eminent 
Dr.  Halley:  — 

"In  calm  weather,  when  the  air  is  inclined  to  rain,  the  mercury 
is  commonly  low. 

"  In  serene,  good  weather,  the  mercury  is  generally  high.  Upon 
very  great  winds,  though  they  be  not  accompanied  with  rain,  the 
mercury  sinks  lowest  of  all,  with  relation  to  the  point  of  compass 
the  wind  blows  upon. 

"In  calm  frosty  weather,  the  mercury  generally  stands  high. 

"Within  the  tropics,  and  near  them,  there  is  very  little  or  no 
variation  of  the  height  of  mercury  in  all  weathers. 

"  The  greater  height  of  the  barometer,  is  occasioned  by  two  con- 
trary winds  blowing  towards  the  place  of  observation,  whereby  the 
air  of  other  places  is  brought  thither  and  accumulated." 

In  regard  to  the  course  of  winds,  and  their  effect  on  the  barometer 
and  weather,  they  are  variable  in  different  countries,  and  th  erefore 
omitted  here. 

Extracts  from  a  Manual  published  by  J.  H.  Belville  of  the  Royal 
Observatory  of  Greenwich. 

*'  Heat  and  moisture  are  the  principal  causes  of  the  variations  in 
the  weight  of  the  atmosphere,  and  necessarily  in  the  variations  in 
the  barometer  at  the  same  station." 

"  The  variations  of  the  barometer,  are  less  within  the  tropics, 
than  in  the  temperate  and  polar  regions  ;  they  vary  in  different 


THE    BAROMETER.  63 

countries  in  the  same  latitude,  and  they  are  greater  in  mountain- 
ous countries,  and  islands.  In  Peru,  the  range  of  the  mercury  is 
about  one-third  of  an  inch — in  London  two  and  a  half  inches,  and 
in  St.  Petersburg,  it  exceeds  three  inches." 

"It  is  not  so  much  the  absolute  height,  as  the  actual  rising  and 
falling  of  the  mercury,  which  determines  the  kind  of  weather  likely 
to  follow." 

"Great  depressions  at  all  seasons  are  followed  by  change  of  wind, 
and  oy  much  ram." 

"Rain  in  some  quantity  may  fall  with  a  high  pressure,  pro- 
vided the  wind  be  in  any  of  the  northerly  points." 

"No  great  storm  ever  sets  in  with  a  steady  rising  barometer." 

"  The  variations  of  the  barometer,  are  always  greater  in  the 
winter  than  in  the  summer." 

"Sudden  depressions  of  the  barometer,  sometimes  occur  in  wea- 
ther apparently  calm.  It  is  almost  an  established  fact,  that  storms 
have  a  circular  motion;  and,  if  when  an  exhaustion,  or  sudden 
diminution  of  the  atmosphere  takes  place,  the  mercurial  column 
happens  to  be  in  the  partial  vacuum  or  centre  of  motion,  the  air  will 
be  at  rest;  while  the  surrounding  air  at  a  greater  distance  from  the 
centre,  will  be  violently  agitated  with  a  less  fall  of  the  barometer." 

N.  B. — In  all  observations  for  this  purpose,  the  rise  and  fall  of  the 
mercury  should  be  reckoned  from  its  mean  height  at  whatever  ele- 
vation the  station  may  be  above  the  sea  level. 

ANEROID  BAROMETER. 

The  Aneroid  Barometer  is  a  new  instrument  for  ascertaining  the 
variations  of  the  atmosphere :  its  action  depends  on  the  effect  produced 
by  the  pressure  of  the  atmosphere  on  a  metallic  box,  from  which  the 
air  has  been  exhausted  and  then  hermetically  sealed:  the  hand  of 
the  Aneroid  can  be  set  to  correspond  with  the  mercurial  barometer, 
by  which  it  should  be  compared  by  turning  a  screw  on  its  back-side. 
This  screw  when  turned  with,  or  against  the  sun,  alters  the  position 
of  the  hand,  and  is  not  to  be  touched  for  any  other  purpose. 

There  is  another  gilt  hand,  called  the  register  or  index,  which  moves 
above  the  other  by  a  nut  or  thumb  piece  which  projects  through  the 
centre  of  the  glass,  to  enable  the  observer  to  register  the  barometer 
hand,  by  which  to  refer  its  movement  for  another  time,  or  in  ascend- 
ing  or  descending  hills,  &c. 

The  Aneroid  Barometer  can  be  carried  and  used  through  any  country 


64 


THE   BAROMETER. 


with  about  the  same  safety  as  a  watch,  and  is,  therefore,  the  most 
suitable  barometer  of  any  now  in  use,  for  measuring  the  height 
of  hills  and  mountains,  in  new  countries. 

The  corrections  for  temperature  for  the  Aneroid,  are  seldom  pre- 
cisely the  same  as  for  the  mercurial  barometer ;  but  the  quantity 
necessary  for  thermometrical  correction  can  be  readily  found,  by 
exposing  the  instrument  to  the  temperature  of  the  external  air  for 
twenty  or  thirty  minutes,  and  set  the  hands  coincident,  then  place  it 
near  the  fire  until  the  thermometer  is  at  ninety  or  a  hundred  degrees ; 
the  variation  of  the  hand,  divided  by  the  variation  in  degrees  of  the 
thermometer,  will  give  the  quantity  for  each  degree. 

MEASUREMENTS  OF  HEIGHTS  WITH  THE  BAROMETER. 

The  following  table,  being  an  extract  from  the  elaborate  table  of 
W.  Galbraith,  A.  M.,  furnishes  another  expeditious  method  for  this 
purpose.  » 

In  this  table,  the  third  column  exhibits  numbers  in  English  feet, 
corresponding  to  the  height  of  the  barometer  (shown  on  its  left,)  in 
inches,  tenths,  and  hundredths,  the  proportional  parts  to  thousandths 
are  given  in  column  headed  A.

EXAMPLE. 


At  the  foot  of  a  hill  the  barometer  indicates  29.54  inches,  then 
carried  immediately  to  the  top  of  the  hill  reads  28.70  inches.  In  the 
table  at  29.54  we  find  28824.1  feet, 

at  28.70  we  find  —28070.5  feet, 


Height  of  hill  753.6  feet. 

To  perform  this  operation  accurately,  when  the  interval  of  time 
exceeds  ten  minutes  between  the  two  observations,  two  persons  should 
take  contemporary  observations,  with  two  Aneroid  Barometers,  one 
at  the  foot,  and  the  other  at  the  top  of  the  hill,  and  correct  each  for 
temperature, 


SYSTEM  OF  SURVEYS  OF  THE  U.  S.  LANDS. 

The  public  lands  of  the  United  States  are  surveyed  in  a  uniform 
mode  established  by  law,  by  lines  run  by  the  cardinal  points  of  the 
compass;  the  north  and  south  lines  coinciding  with  the  true  meri- 
dian, and  the  east  and  west  lines  intersecting  them  at  right  angles, 
giving  to  the  tracts  thus  surveyed  the  rectangular  form. 

The  public  lands  are  laid  off  and  surveyed,  primarily,  into  tracts 
of  six  miles  square  as  near  as  practicable,  called  townships,  contain- 
ing 23040  acres  each.  The  townships  are  subdivided  into  thirty-six 
tracts,  called  sections,  each  of  which  is  one  mile  square,  as  near  as 
may  be,  and  contains  640  acres.  Any  number,  or  series,  of  con- 
tiguous townships,  situated  north  or  south  of  each  other,  constitute 
a  Range. 

To  obtain  and  preserve  a  convenient  and  uniform  mode  of  num- 
bering the  ranges  and  townships,  it  is  usual  in  commencing  the  sur- 
vey of  an  insulated  body  of  public  lands  to  run,  or  assume  two  stand" 
ard  lines,  as  the  basis  of  the  survey  to  be  made  therein.  One  of 
these  standard  lines  is  run  due  north  and  south,  and  is  called  the 
principal  meridian,  to  which  the  ranges  are  parallel,  and  from  which 
they  are  numbered  eastward  and  westward.  The  other  standard 
line  is  run  due  east  and  west,,  and  is  called  the  base  line,  from  which 
the  townships  are  numbered,  northward  and  southward. 

To  distinguish  from  each  other,  the  systems,  or  series  of  surveys 
thus  formed,  the  several  principal  meridians  are  designated  by  pro- 
gressive numbers.  Thus  the  meridian  running  north  from  the  mouth 
of  the  Great  Miami  river,  is  called  the  first  principal  meridian :  the 
meridian  running  north  through  the  centre  of  the  State  of  Indiana,  is 
called  the  second  principal  meridian:  that  running  nortli  from  the 
mouth  of  the  Ohio  river,  through  the  State  of  Illinois,  is  called  the  third 
principal  meridian:  that  running  north  from  the  mouth  of  the  Illinois 
river,  through  the  States  of  Illinois  and  Wisconsin,  is  called  the  fourth 
principal  meridian:  and  that  running  north  from  the  mouth  of  the 
Arkansas  river,  through  the  states  of  Missouri  and  Iowa,  is  called 
the  fifth  principal  meridian. 


SYSTEM   OF    SURVEYS   OF 


CORRECTION  LINES  correct  the  error  that  would  otherwise  arise 
from  the  coiivergency  of  meridians,  and  arrest  that  proceeding  from 
the  inaccuracies  of  measurement.  They  are  run  due  east  and 
west  at  stated  distances,  generally  at  the  end  of  every  tenth  town- 
ship, and  each  forms  a  base  for  the  townships  north  of  it.  Each 
range  of  townships  should  be  made  as  much  over  six  miles  in  width 
on  each  base  and  correction  line  as  it  will  fall  short  of  the  same  svidth 
where  it  closes,  on  the  next  correction  line  north,  the  excess  or  de- 
ficiency of  width  being  always  thrown  into  the  last  half  mile,  on  all 
of  the  lines  closing  out  to  the  west  boundary  of  each  township. 

This  mode  of  executing  the  public  surveys,  conduces  more,  per- 
haps, than  any  other  which  could  be  devised,  to  the  simplicity,  regu- 
larity, and  symmetry  of  the  work,  and  to  the  ease  and  certainty  with 
^vhich  any  tract  may  be  identified. 

The  public  lands  are  surveyed  by  Deputy  Surveyors,  appointed  by 
Ae  Surveyor  General  of  the  State  or  Territory,  in  which  the  dis- 
trict assigned  to  each  deputy  may  be  situated ;  their  duties  are  pre- 
scribed by  general  and  special  instructions. 

OF  SUBDIVIDING  TOWNSHIPS. 

Each  township  is  laid  off  and  surveyed  into  thirty-six  sections  as 
near  as  may  be  of  one  mile  square,  by  lines  running  north  and  south, 
crossed  by  others  running  east  and  west.  The  sections  are  known 
and  designated  by  progressive  numbers,  beginning  at  the  north-east 
corner  of  the  township,  and  numbering  westward  and  eastward  alter- 
nately, as  shown  in  the  following  diagram.

UNITED    SlATEri   LANDS.  69 

Quarter  section  corners  are  established  equidistant  between  the 
section  corners,  except  on  the  section  lines  closing  on  the  north  and 
west  boundaries  of  townships,  on  which  they  are  set  at  forty  chains 
from  the  last  section  corner,  and  the  excess  or  deficiency  of  measure 
(if  any)  is  carried  out  into  the  last  half  mile,  and  cast  upon  the 
north  and  west  sides  of  the  township,  as  required  by  law.  Various 
instructions  have  been  given  by  Surveyors  General,  to  Deputy  Sur- 
veyors, for  the  purpose  of  accomplishing  an  equitable  and  lawful 
subdivision  of  townships  into  sections,  none  of  which,  it  is  believed, 
will  effect  this  object  better  than  the  system  adopted  in  1850,  by 
The  surveyor  general  of  Ohio,  Indiana,  and  Miohigan;  by  which  the 
true  course  and  measurement  of  every  line  is  given,  and  the  ine- 
qualities of  measurement  proportionally  carried  to  every  sectional 
line.  This,  together  with  the  closing  of  the  section  lines  at  post  on 
the  north  and  west  boundaries  of  the  townships,  (which  were  for- 
merly closed  at  the  intersection  of  the  lines  run  to  them,  whether  at 
~-ost  or  not,)  has  much  improved  the  symmetry  and  equality  of  the 
subdivision  of  townships. 

An  act  of  Congress  of  the  24th  May,  1824,  authorizes  a  departure 
from  the  ordinary  mode  of  surveying  the  public  land,  on  any  river, 
lake,  or  bayou,  whenever,  in  the  opinion  of  the  President  of  the 
United  States,  the  public  interest  would  be  promoted  thereby,  so  ag 
to  survey  such  lands,  in  tracts  of  two  acres  in  width  fronting  ox 
such  river,  lake,  or  bayou,  and  running  back  to  the  depth  of  fort^ 
acres. 

ON  SUBDIVIDING  SECTIONS,  AND  RE-ESTABLISHING  OF  EXTINCT  LINES 
AND  CORNERS:  DEDUCED  FROM  THE  ACTS  OF  CONGRESS,  IN  REGARD 
TO  THE  SURVEYS  OF  THE  PUBLIC  LANDS  ;  AND  THE  CONSTRUCTIONS 
AND  USAGES  THEREON. 

The  general  principles  on  which  the  public  lands  are  surveyed, 
have  already  been  given ;  but  the  county  surveyors  and  purchasers 
of  these  lands,  are  more  immediately  interested  in  the  proper  method 
of  subdividing  sections  into  such  tracts  as  are  sold  to  purchasers  from 
the  United  States  land  offices;  and  the  re-establishing  of  extinct  lines 
and  corners,  when  from  any  cause  they  are  lost  or  cannot  be  found. 
In  the  regular  surveys  of  the  public  lands,  no  other  lines  are 
actually  run  and  marked  by  the  Deputy  Surveyors  of  the  United 
States,  than  township  lines,  and  sections,  or  subdivisional  lines  of 


70  SYSTEM   OP   SURVEYS 

townships,  into  sections;  on  all  of  these  lines,  no  other  than  section 
and  quarter  section  corners  are  established;  except  meander  cor- 
ners at  the  end  of  all  fractional  section  lines  which  close  on  rivers, 
lakes,  &c. 

All  sections  in  a  full  township,  except  those  which  are  bounded  by 
its  north  and  west  sides,  are  treated  as  full  sections  in  their  sales 
and  subdivisions;  and  also,  the  south  half  of  sections  on  the  north 
boundary,  and  the  east  half  of  sections  on  the  west  boundary  of  each 
full  township,  are  sold  and  subdivided  as  full  half  sections.  Section 
sixteen  in  each  township  is  reserved  for  school  purposes,  and  is  not,  there- 
fore, subject  to  private  entry. 

From  various  causes  (elsewhere  treated  of  in  this  work)  section 
lines  do  not  always  correctly  coincide  with  the  cardinal  points ;  nor 
will  their  measurement  in  all  cases  be  found  exactly  eighty  chains  or 
one  mile  in  length.  (See  article  on  measurement  with  the  chain.) 
Quarter  section  corners,  especially  in  the  older  surveys,  may  not 
always  be  found  equidistant  between  the  section  corners.  This  de- 
fect arises  in  most  oases,  it  is  believed,  from  difficult  or  careless 
measurement  with  the  chain. 

Notwithstanding  such  errors,  all  corners  that  can  be  klentified 
by  the  original  field  notes,  or  other  unquestionable  testimony,  must 
be  regarded  as  the  original  corners,  a*id  for  that  purpose  should  be 
perpetuated  with  new  posts  and  bearings  when  the  old  ones  decay. 

EXTINCT  LINES  AND  CORNERS. 

When  a  Section  corner  cannot  be  identified  by  the  original  field  notes, 
or  by  clear  and  unquestionable  testimony,  run  a  right  line  between 
the  nearest  noted  station  trees,  north  and  south,  and  east  and  west 
of  the  lost  section  corner^  if  there  be  any  such  trees  within  the  dis- 
tance of  the  nearest  quarter  section,  or  section  corners ;  but  if  no 
station  trees  be  found,  then  between  the  nearest  quarter  section  or 
section  corners,  arid  at  the  point  of  intersection  of  these  two  lines 
re-establish  the  section  corner,  with  new  bearings  from  it  to  the  near- 
est and  most  durable  object*;  which  of  course  should  be  recorded 
with  the  survey. 

^Extinct  Quarter  Section  corners,  except  on  fractional  section  lines,  if 
not  identified  as  above  stated  for  section  corners,  must  be  re-estab- 
lished equidistant  between  the  section  corners,  in  a  right  line  be- 
tween the  nearest  noted  station  trees  each  side  of  it,  if  there  be

the  north  and  west  boundaries  of  townships,  must  be  re-established  ac- 
cording to  the  original  measurement  thereof,  at  forty  chains  from  the 
last  interior  section  corner  to  wards  the  township  line.  For  an  example, 
suppose  the  line  between  sections  3  and  4,  or  18  and  19,  to  be  81.30 
chains,  according  to  the  original  survey,  and  by  the  measurement  of 
the  county  survey,  80.90  chains.  Then  say  as  81.30:  80.90: :  40.00 
to  ==  39.81J.  Thus  39  chains  and  81 J  links  is  the  distance  the 
quarter  section  corner  must  be  established  from  the  last  interior 
section  corner,  according  to  the  measure  of  the  county  surveyor. 

Lost  or  extinct  Township  corners,  except  on  correction  lines,  should 
be  restored  in  the  same  manner  as  already  given  for  section  corners; 
and  extinct  quarter  section  corners  on  township  lines,  should  be  re- 
stored in  the  same  manner  as  those  on  interior  section  lines. 

In  subdividing  townships  into  sections,  the  section  lines  which 
close  on  the  north  and  west  boundaries  of  townships,  have  not  al- 
ways been  closed  at  the  section  corners  which  were  established  on 
the  survey  of  the  township  lines ;  but  at  such  points  on  their  bound- 
aries, as  the  first  lines  run  to  them  may  have  intersected. 

Wherever  this  has  been  done  on  the  north  and  west  boundaries  of 
townships,  a  new  quarter  section  corner  must  be  established,  equi- 
distant between  the  corners  of  all  such  irregular  closing  lines;  for, 
the  section  and  quarter  section  corners  established  on  the  survey  of 
these  boundaries,  belong  exclusively  to  the  adjoining  township.  Con- 
sequently, to  restore  lost  or  extinct  section  corners,  that  were  esta- 
blished on  the  north  and  west  boundaries  of  townships,  during  their 
subdivisions  into  sections  as  above  mentioned,  the  section  lines 
closing  at  these  corners,  must  be  retraced  to  them.  But  to  restore 
lost  section,  or  quarter  section  corners,  that  were  established  on  the 
original  survey  of  the  township  lines,  these  boundaries  should  be 
carefully  retraced  and  measured,  and  the  lost  section  and  quarter 
section  corners  should  be  re-established  at  their  proportional  distance 
from  each  other,  between  known  corners.  The  only  exception  to 
this  rule  is,  when  it  is  clear  that  the  section  lines  have  been  regu- 
larly run  according  to  instructions,  and  can  be  correctly  retraced  to 
the  township  line.  The  section  corners  should  then  be  re-  established 
at  such  intersections. 


72  SYSTEM   OF   SURVEYS   OF 

Extinct  or  obliterated  lines  may  be  restored  by  running  right  lines 
between  re-established  and  other  known  corners;  except  noted  sta- 
tion trees  be  found  between  them,  when  the  lines  between  corners 
must  conform  to  the  noted  station  trees. 

It  may  be  remarked  here  that  no  surveyor  can  legally  alter  or 
correct  the  original  surveys.  It  is  his  duty  to  restore  them  as  far  as 
practicable  to  their  original  condition. — In  making  resurveys  of  the 
public  lands,  such  directions  and  absolute  length  must  be  given  to 
each  line  as  were  given  to  them  by  the  original  surveyor,  whether 
the  retracing,  courses  and  measurements,  agree  with  the  original 
survey  or  not;  except  otherwise  directed  by  the  Surveyor  General, 
or  the  Commissioner  of  the  general  Land  Office. 

BEARING  TREES,  &o. 

Bearing  trees,  to  corners,  have  a  blaze  with  a  notch  in  them  near  the 
ground  and  facing  the  corner;  sometimes  the  letters  B  T  are  found 
in  the  blaze  above  or  below  the  notch,  which  are  the  initials  of  Bear- 
ing Tree.  Their  size,  kind  of  timber,  course  and  distance  from  the 
corner  post,  is  given  in  the  field  notes  of  the  survey. 

Section,  and  quarter  section  trees  are  "faced  off"  on  the  side  to- 
wards the  corner,  four  or  five  feet  from  the  ground.  The  quarter 
section  trees  are  marked  thus  J  S.  At  section  corners  these  trees 
are  marked  with  the  number  of  the  Range,  Township  and  Section, 
thus,  R.  24  W.  T.  45  N.  S;  15.*  There  is  no  note  made  of  these 
trees  in  the  field  books,  unless  they  are  bearing  trees  also;  they  are 
marked  for  the  purpose  of  giving  information  at  the  corner,  of  the 
number  of  the  sections  which  corner  there,  a-nd  also,  the  number  of 
the  township  and  range.  Station  trees  on  the  lines,  are  notched  with 
two  notches  on  each  side  in  the  direction  of  the  line,  and  their  eize, 
kind  of  timber,  and  distance  from  the  last  section  corner  are  given 
in  the  field  notes. 

SUBDIVISION  LINES  OF  SECTIONS. 

The  subdivisions  of  whole  sections  into  such  tracts  as  are  sold  by  the 
land  officers  of  the  United  States,  to  purchasers  of  public  lands,  are 
made  by  running  right  lines  between  the  quarter  section  corners,  on 
the  north  and  south,  and  east  and  west  sides  of  the  section;  and  at 
the  intersection  of  these  lines  is  established  the  common  corner  for

its  four  quarters,  without  regard  to  the  quantity  of  land  contained 
in  each  of  them.  These  quarter  sections  are  sold  as  containing  160 
acres  each,  and  are  designated  as  the  N.  E.,  N.  W.,  S.  E.  and  S.  "W. 
quarters. 

Quarter  sections  are  divided  into  halves,  by  a  north  and  south 
line,  equidistant  by  measurement  between  its  east  and  west  corners. 
These  tracts  of  land  are  supposed  to  contain  eighty  acres  each,  and 
are  designated  as  the  east  and  west  half  of  the  quarter  section. 

Furthermore  a  quarter  section  is,  also,  divided  into  quarters  by 
lines  run  north  and  south,  and  east  and  west,  equidistant  between 
its  four  corners,  and  at  the  intersection  of  these  lines  at  the  centre 
of  the  quarter  section,  is  established  the  common  corner  to  its  four 
quarters.  These  quarters  of  a  quarter  section  are  supposed  to  con- 
tain forty  acres  each,  and  are  described  as  the  N.  E.,  N.  W.,  S.  E. 
and  S.  W.  quarters  of  the  quarter  section.

Quarter  sections  adjoining  the  north  and  west  boundaries  of  town- 
ships, are  deemed  to  be  fractional,  and  therefore,  may  contain  more 
or  less  land,  than  is  given  to  other  quarter  sections  within  the  town- 
ships; they  are  sold  or  surveyed  according  to  their  plats  in  the  land 
offices.

before  mentioned  in  the  subdivisions  of  townships  into  sections,  may 
not  precisely  agree  with  the  cardinal  points  of  the  compass. — There-

lines,  which  close  on  meandered  streams,  lakes,  £c. ;  the  quarter 
section  line  should  be  run  with  an  intermediate  course  between  the 
section  lines ;  and  the  fractional  quarter  sections  thereof,  should  be 
divided  in  like  manner. 

The  subdivisions  of  fractional  sections,  are  indicated  on  the  mapa

AN  ACT  CONCERNING  THE  MODE  OF  SURVEYING  THE 

PUBLIC  LANDS  OF  THE  UNITED  STATES. 
§  I.  Be  it  enacted,  $c.  That  the  Surveyor  General  shall  cause  all 
those  lands  north  of  the  river  Ohio,  which,  by  virtue  of  the  act  en- 
titled, "An  act  providing  for  the  sale  of  the  lands  of  the  United 
States  in  the  territory  northwest  of  the  river  Ohio,  and  above  the 
mouth  of  the  Kentucky  river,"  were  subdivided,  by  running  through 
the  townships  parallel  lines,  each  way,  at  the  end  of  every  two  miles, 
and  by  marking  a  corner  on  each  of  the  said  lines,  at  the  end  of  every 
mile,  to  be  subdivided  into  sections,  by  running  straight  lines,  from  the 
mile  corners  thus  marked  to  the  opposite  corresponding  corners,  and 
by  marking,  on  each  of  the  said  lines,  intermediate  corners,  as  near 
as  possible  equidistant  from  the  corners  of  the  sections  of  the  same. 
And  tlie  said  Surveyor  General  shall  also  cause  the  boundaries  of  all 
the  half  section,  which  had  been  purchased  previous  to  the  first  day  .of 
July  last,  and  on  which  the  surveying  fees  had  been  paid  according 
to  law  by  the  purchaser,  to  be  surveyed  and  marked,  by  running 
straight  lines  from  the  half  mile  corners  heretofore  marked,  to  the 
opposite  corresponding  corners ;  and  intermediate  corners  shall  at 
the  same  time,  be  marked  on  each  of  the  said  dividing  lines,  as 
nearly  as  possible  equidistant  from  the  corners  of  the  half  section  on 
the  same  line:  Provided,  That  the  whole  expense  of  surveying  and 
marking  the  lines,  shall  not  exceed  three  dollars  for  every  mile  whieU 
has  not  yet  been  surveyed,  and  which  shall  be  actually  run,  sur«

making  the  subdivisions  directed  by  this  section,  shall  be  defrayed 
out  of  the  moneys  appropriated,  or  which  may  be  hereafter  appro- 
priated, for  completing  the  surveys  of  the  public  lands  of  the  United 
States. 

\  II.  That  the  boundaries  and  contents  of  the  several  sections, 
half  sections,  and  quarter  sections,  of  the  public  lands  of  the  United 
States,  shall  be  ascertained  in  conformity  with  the  following  princi- 
ples, any  act  or  acts  to  the  contrary  notwithstanding: — 1st.  All  the 
corners  marked  in  the  surveys  returned  by  the  Surveyor  General, 
or  by  the  surveyor  of  the  land  south  of  the  state  of  Tennessee  re- 
spectively, shall  be  established  as  the  proper  corners  of  sections, 
or  subdivisions  of  sections,  which  they  were  intended  to  designate; 
and  the  corners  of  half  and  quarter  sections,  not  marked  on  said 
surveys,  shall  be  placed  as  nearly  as  possible  equidistant  from  those 
two  corners  which  stand  on  the  same  line.  2d.  The  boundary  lines, 
actually  run  and  marked  in  the  surveys  returned  by  the  Surveyor 
General,  or  by  the  surveyor  of  the  land  south  of  the  state  of  Ten- 
nessee, respectively,  shall  be  established  as  the  proper  boundary 
lines  of  the  sections,  or  subdivisions  for  which  they  were  intended ; 
and  the  length  of  such  lines,  as  returned  by  either  of  the  surveyors 
aforesaid,  shall  be  held  and  considered  as  the  true  length  thereof. 
And  the  boundary  lines  which  shall  not  have  been  actually  run  and 
marked  as  aforesaid,  shall  be  ascertained  by  running  straight  lines 
from  the  established  corners  to  the  opposite  corresponding  corners; 
but  in  those  portions  of  the  fractional  townships,  when  no  such  oppo- 
site corresponding  corners  have  been  or  can  be  fixed,  the  said  bound- 
ary lines  shall  be  ascertained  by  running  from  the  established  corners, 
due  north  and  south  or  east  and  west  lines,  as  the  case  may  be,  to  the 
water  course,  Indian  boundary  line,  or  other  external  boundary  of 
such  fractional  township.  3d.  Each  section,  or  subdivision  of  section, 
the  contents  whereof  shall  have  been,  or  by  virtue  of  the  first  section 
of  this  act,  shall  be  returned  by  the  Surveyor  General,  or  by  the  sur- 
veyor of  the  public  lands  south  of  the  state  of  Tennessee,  respectively, 
shall  be  held  and  considered  as  containing  the  exact  quantity  ex- 
pressed in  such  return  or  returns ;  and  the  half  sections  and  quarter 
sections,  the  contents  whereof  shall  not  have  been  thus  returned, 
shall  be  held  and  considered  as  containing  the  one  half,  or  the  one 
fourth  part,  respectively,  of  the  returned  contents  of  the  section  ol 
which  they  make  part.

GEOLOGICAL  AND  TOPOGRAPHICAL  IN  CONNEXION  WITH 
LINEAR  SURVEYS. 

GEOLOGICAL   SURVEYS. 

In  connexion  with  the  linear  surveys  of  new  districts  of  country, 
the  surveyors  have  good  opportunities  to  make  geological  examina- 
tions, and  to  collect  specimens  of  minerals  that  may  be  discovered 
in  the  course  of  their  work.  Such  specimens,  when  submitted  to  a 
scientific  and  practical  geologist,  will  enable  him  to  determine  the 
true  character  of  such  new  districts,  and  what  kinds  of  products 
may  be  expected  to  be  derived  from  them. 

It  is,  therefore,  of  much  importance,  that  surveyors  of  the  public 
land  should  possess  or  acquire,  at  least  a  sufficient  knowledge  ol 
geology,  to  enable  them  to  make  a  proper  collection  of  geological 
specimens;  and  also,  to  observe  the  character,  stratifications,  dip,  &c., 
of  any  rocks  in  place,  or  other  mineral  deposits. 

Such  services  afford  pleasure  and  profit  to  the  surveyors,  while 
they  contribute  to  the  public  interest,  and  to  science.  A  system  of  sur- 
veys for  this  purpose  has  been  partly  tested ;  but  while  in  successful 
progress,  it  was  interrupted  by  the  death  of  the  geologist,  the  la- 
mented Dr.  Douglass  Houghton,  while  he  was  engaged  in  prosecuting 
a  geological,  in  connexion  with  the  linear  survey,  of  the  south  coast 
of  Lake  Superior. 

This  system  possesses  many  advantages  over  any  other  that  has 
been  adopted,  for  obtaining  a  general  geological  knowledge  of  new 
and  unsettled  countries,  the  expense  of  which  is  trifling  compared 
with  an  independent  geological  survey;  also,  such  surveys  are  of 
great  value  when  known,  iri  directing  emigrants  to  the  country  suit- 
able for  their  occupation  or  enterprise,  and  thus  effect  an  early  and 
judicious  development  of  its  resources. 


UNITED   STATES  LANDS.  It 

A  system  of  linear  and  geological  surveys  may  be  satisfactorily 
prosecuted,  by  the  appointment  of  a  competent  geologist  to  a  clerk- 
ship in  each  Surveyor  General's  office:  the  Deputy  Surveyors  being 
made  assistant  geologists  to  execute  the  field  work,  under  a  well  di- 
gested system  for  that  purpose,  who  should  make  their  report,  and 
return  their  specimens  to  the  Surveyor  General,  when  the  geologist 
under  him  can  investigate  such  reports,  and  embody  the  whole  in 
one  connected  geological  report,  so  far  as  such  surveys  extend* 

By  this  system,  it  will  be  seen  that  the  position  of  all  mineral  de- 
posits from  which  specimens  are  taken,  may  be  precisely  located  by 
measure  on  the  survey,  and  be  as  easily  found  as  the  various  section, 
quarter  section,  and  other  subdivisions  themselves,  a  consideration 
of  much  importance,  which  any  independent  geological  or  other 
system  yet  adopted  fails  to  do. 

TOPOGRAPHICAL  SURVEYS. 

The  general  topographical  features  of  new  districts  of  country  are 
of  much  interest  to  the  public,  and  especially  to  emigrants.  Such 
surveys  can  be  made  with  but  little  expenditure  of  time  while  the 
linear  surveys  are  in  progress,  by  a  proper  use  of  the  Aneroid  Ba- 
rometer, for  the  purpose  of  determining  on  the  lines,  the  height  of 
hills,  ledges,  &c.,  above  the  valleys;  (see  article  on  the  use  of  the 
Aneroid  Barometer)  and  by  observing  also,  the  course  and  angle  of 
elevation  or  depression  of  distant  noticeable  objects,  on  the  summits 
of  hills,  mountains,  ledges,  &c.,  and  in  the  valleys  below  them;  which 
can  be  seen  from  two  or  more  stations  on  the  lines  at  the  time  they 
are  being  run.  And  further,  when  running  the  meanderings  of 
the  shores  of  rivers  or  lakes,  bearings  and  angles  of  elevation  may 
be  also  taken  to  conspicuous  objects  on  islands,  rocks,  sand-bars,  &c., 
which  can  be  seen  from  their  shores.  To  these  observations  should 
be  added,  sketches  of  landscapes,  ledges,  and  whatever  else  may 
interest  the  inquiring  mind. 

Such  bearings,  and  angles  of  elevation  and  depression,  form  tri- 
angles with  a  given  base  to  each,  which  are  good  data  for  mapping, 
or  trigonometrical  calculations,  to  establish  the  course,  distance, 
elevation  or  depression,  from  a  fixed  point  within  the  survey  of  every 
object  with  which  they  are  connected.* 

*  In  making  calculations  for  the  heights  of  distant  objects,  the  table  for  correc- 
tions for  curvature  and  refraction,  will  give  the  number  of  feet  tc  be  added  to  their 
height;  on  the  account  of  the  difference  of  the  apparent  and  true  level  from  th« 
point  of  observation.

SURVEYORS*    OUTFIT.  79 

A  useful  application  of  a  series  of  triangles  can  be  made  across 
lakes,  bays,  harbours,  &c.,  commencing  from  a  correctly  measured 
base*  on  or  near  their  coasts,  so  connected  with  every  point  or  object 
on  their  shores  or  within  their  waters,  that  the  meanderings  of 
their  shores,  and  position  of  islands,  sand-bars,  soundings  or  other 
objects  can  be  correctly  delineated  on  a  map,  by  course  and  distance 
from  any  known  point  of  survey.  A  full  description  of  the  above 
principles  'with  proper  examples,  would  occupy  too  much  space  to 
be  admitted  here,  but  it  is  believed  that  the  well  qualified  practical 
surveyor,  will  find  but  little,  if  any  difficulty  in  applying  these  princi- 
ples to  any  survey  that  may  require  their  use.

SURVEYORS     OUTFIT.  81 

Remarks. 

Camp  pails,  or  kettles,  should  be  made  of  heavy  tin,  and  the 
covers  and  ears  riveted,  where  they  would  be  likely  to  separate  when 
exposed  to  the  fire. 

The  most  approved  form  of  a  camp  pail  is  an  elliptical,  or  oblong 
bottom,  with  upright  sides.  The  largest  pail  should  be  made  about 
nine  inches  in  depth,  and  to  hold  twelve  quarts,  or  more;  the  other 
three  of  a  less  size,  so  as  to  fit  inside  of  the  largest  one. 

The  basins  are  made  six  or  seven  inches  in  diameter,  and  one  and 
a  half  inch  in  depth ;  they  serve  in  the  place  of  plates,  cups,  soup 
and  meat  dishes,  &c.  The  knives,  forks,  and  spoons,  should  be  of 
a  small  size,  except  one  large  spoon  for  mixing  bread,  £c. 

Flour  is  mixed  for  bread  on  a  cloth  of  cotton  drilling,  of  about 
one  yard  square.  It  is  done  as  follows: — 

Spread  the  cloth  on  a  blanket,  folded  and  laid  on  the  ground; 
pour  enough  flour  upon  it  for  a  mixing,  and  make  a  hollow  in  it; 
then  pour  in  some  lard  from  the  can,  and  add  saleratus  and  salt 
dissolved  in  warm  water,  stirring  the  flour  with  a  spoon  to  a  proper 
consistency  for  kneading  with  the  hand,  taking  care  not  to  reach 
the  bottom  of  the  flour  so  as  to  wet  the  cloth. — Bake  the  loaves  in  the 
frying  pans  before  the  fire,  and  when  done,  fold  the  cloth,  and  lay  it 
aside  for  future  use. 

TENTS. 

The  soldiers'  tent  made  of  good  firm  cotton  drilling,  will  answer 
the  purpose  very  well,  in  any  country.  The  Marquee,  however,  is 
tetter  in  a  prairie  country.  Another  tent,  much  approved  by  some 
feurveyors,  for  a  timbered  country,  is  made  of  good  cotton  drilling: 
when  pitched,  nearly  resembles  a  little  more  than  one  half  of  a  steep 
roofed  building,  with  its  share  of  the  ends.  It  can  be  quickly 
pitched  with  poles,  and  crotches,  by  having  suitable  eyelets,  and 
strings  at  the  bottom,  and  at  the  ridge,  and  front.  It  has  four  or 
five  breadths  of  cloth,  about  four  and  one  third  yards  in  length ;  the 
end  may  be  made  of  cotton  sheeting,  of  the  form  above  indicated. 
This  tent  possesses  the  advantage  of  being  less  in  weight  and  bulk, 
than  any  other  in  use  among  surveyors :  therefore,  very  suitable  to 
be  used  when  the  carrying  is  done  by  men. 


82  SURVEYORS'  OUTFIT. 

CONVEYING  PACKS  WITH  HORSES  OR  MULES. 

The  man  who  manages  the  pack  horse,  should  be  an  experienced 
woodsman,  capable  of  finding  his  way  with  the  help  of  a  pocket  com- 
pass, to  any  point  within  the  district  to  be  surveyed,  that  may  be 
designated  by  the  surveyor. 

The  "sack  Indian  saddle"  is  the  best  in  use  for  the  purpose  of 
packing,  but  pack  saddles  may  be  made  in  the  form  of  those  used 
by  most  of  the  Indian  tribes.  They  should  have  attached  to  them 
a  stout  girt,  breast  strap,  and  breeching,  and  be  well  padded,  or  have 
a  folded  blanket  under  it,  when  in  use. 

Suitable  straps  with  buckles  should  be  provided,  to  tightly  buckle 
around  near  the  ends  of  each  bag,  or  articles  done  up  with  a  wrap- 
per and  cord,  which  are  intended  for  side  packs.  Before  buckling 
these  straps,  a  loop  made  of  strong  cord  about  ten  inches  long, 
should  be  slipped  on  to  each ;  after  buckling  the  straps,  these  loops 
will  be  hitched  over  the  horns  of  the  saddle,  and  wound  around  them 
if  too  long:  thus  each  side  pack  lies  lengthwise  of  the  horse,  sus- 
pended by  the  loops  from  the  horns  of  the  saddle. 

Between  the  side  packs  other  loose  articles  may  be  placed,  such 
as  tin  pails,  frying  pans,  &c.  These  bags  and  other  loading,  should 
be  well  balanced,  and  bound  to  the  horse  and  saddle,  with  a  cord  of 
suitable  length.  That  the  horse  may  be  easily  found  when  not  at 
work,  a  small  bell  should  be  fastened  to  his  neck,  with  a  strap  and 
buckle.  A  "spancil"  should  also  be  provided,  made  of  leather  with 
two  buckles,  for  fastening  the  forefeet  of  the  animal  nearly  together, 
that  he  may  not  go  astray. 

CONVEYING  PACKS  WITH  MEN. 

When  packs  cannot  be  carried  on  horses,  or  mules,  men  are  em- 
ployed for  that  purpose,  and  should  be  provided  with  suitable  pack 
straps.  The  "portage  strap"  is  sometimes  used:  it  is  made  of 
leather,  and  is  ten  or  twelve  feet  in  length';  the  middle  part  is  two 
feet  long,  and  three  inches  broad  in  the  middle,  and  tapers  each  way; 
at  each  end  of  this  broad  part  is  secured  a  thong  of  leather,  suffi- 
ciently strong  to  support  the  pack.  Each  end  of  the  portage  strap 
is  tied  around  the  pack  to  be  carried:  the  broad  part  passes  over 
the  forehead,  or  chest  of  the  person  who  conveys  it. 

Another  "pack  strap"  in  common  use,  is  made  of  five  straps; 


SURVEYORS'  OUTFIT.  83 

*wo  of  them  are  buckled  around  the  pack  near  each  end,  and  two 
are  slipped  under  them  and  sewed  together,  in  such  a  manner,  as 
when  buckled,  to  form  shoulder  straps ;  the  fifth  strap  is  about  three 
inches  broad  at  the  middle,  and  tapers  each  way,  and  is  buckled  at 
each  end  to  the  other  straps,  in  such  a  manner  as  to  pass  over  the 
forehead  when  in  use;  the  pack  is  put  on  in  a  similar  manner  to 
that  of  a  peddler's  pack. 

Packs  which  are  carried  by  men,  to  supply  a  surveying  company 
in  the  field,  usually  weigh  from  seventy-five  to  a  hundred  and  twenty 
pounds  each. 

SURVEYORS'  WEARING  APPAREL 

The  common  wool  hat  is  best  for  any  season  of  the  year,  espe- 
cially in  timbered  land. 

Trowsers  should  be  made  large,  and  of  strong  cloth. 

A  light  coat,  or  frock,  should  be  provided,  well  supplied  with  water  • 
proof  pockets,  to  keep  books  and  papers  dry  in  wet  weather,  and  a 
light  India  rubber,  or  water  proof  cape  should  also  be  provided  to 
keep  the  compass  dry,  when  travelling  in  wet  weather. 

Flannel  for  under  clothes,  is  preferable  to  cotton,  for  all  seasons 
and  kinds  of  weather. 

Boots  may  be  made  of  good  kip  skin,  and  rather  larger  than  for 
ordinary  use ;  the  fronts  of  the  legs  should  be  cut  narrower,  and  the 
backs  wider,  than  is  usual  to  cut  them.  A  thick  single  sole  pro- 
jecting about  one  quarter  of  an  inch  from  under  the  upper  leather, 
and  well  nailed  over  the  bottoms  with  sparables,  or  tacks,  are  the 
most  durable.  The  nails  keep  the  feet  from  slipping,  and  the  broad 
sole  protects  the  upper  leather  from  wearing  against  bushes,  grass, 
&c.  A  large  silk  handkerchief,  of  any  colour  but  red,  to  tie  over 
the  ears  and  neck,  is  a  good  protection  from  flies  and  musquitoes. 

DEPOTS  IN  ADVANCE  OF  A  SURVEY. 

Much  difficulty  has  sometimes  been  experienced  by  surveyors  in 
new  and  unsettled  countries,  in  providing  an  ample  supply  of  pro- 
jvisions  for  their  parties  while  engaged  in  large  surveys  of  exterior 
ttownship  lines.  This  difficulty  can  be  overcome  in  a  great  measure 
by  the  use  of  the  solar  compass.  The  latitude  of  the  township  cor- 
ner, which  is  to  be  the  commencing  point  of  the  survey,  must  be 
[determined  with  the  instrument  to  be  used  in  executing  the  work; 


84  SURVEYORS'  OUTFIT. 

then  convey  the  supplies  by  the  most  feasible  route,  to  the  desh 
position  within  the  district  to  be  surveyed,  and  deposit  it  secure 
from  storms  and  wild  animals,  on  or  near  some  stream,  lake,  Indi; 
trail,  or  other  conspicuous  object  that  can  be  recognised,  in  the  1 
titude  of  any  east  and  west  township  line;  which  may  be  determin 
by  allowing  5X  12/x  of  latitude  for  each  township  of  six  miles  nor 
or  south  of  the  commencing  corner  of  the  survey.  If  the  townsh 
line,  when  run,  should  pass  a  few  chains  to  the  right  or  left  of  t! 
depot  thus  made,  it  can  be  found  in  a  few  minutes. 

This  method  of  depositing  supplies  of  provisions  in  advance  of  i 
•urvejed  lines,  has  been  successfully  practised  by  the  author
